New work has been framed – these pieces consider the potential for the human eye to perceive the Earth’s magnetic field. Research shows birds have this capability activated by molecules in the retina of the eye when excited by blue light. The molecules produce radical pair electrons sensitive to the magnetic field and as these molecules are found within the photoreceptor cells it is possible birds may visualise the magnetic field lines to aid navigation. A similar molecule is also found in the human eye and I am speculating that this is a sense we may once have experienced and could tap into again. It is of course the brain that must receive a signal from the eye by which we see. Independently of the cryptochrome molecule, research monitoring alpha wave activity shows the human brain does appear to be sensitive to a magnetic field albeit unconsciously.

Framework made a neat job of the frames enabling the magnets to be released to reset the iron filings if necessary. The Compass Eye doesn’t have glass and maybe that was a mistake but I prefer the thin frame.

Progress is being made on new work Breath of Stars. This will be a screen based work triggered by cosmic ray activity. Every time an event is registered by a photomultiplier attached to a 5cm square piece of plastic scintillator, a star burst video image will flash up on the screen. The size of the starburst will correspond to the energy of the particle that has just arrived from space. The starburst videos are made in Adobe After Effects using footage from my cloud chamber experiments.

I have got some help with coding from gaming programmer Jamie Howard so am not feeling so out of my depth in the python maze. One problem we may have though is the shortage of Raspberry Pi processors. It could be months before we are able to get one with a high enough spec to process the video layering. In the meantime I am testing ideas and creating video clips.

It was wonderful to see so many people visiting the first Open Studios at Thames-side since 2019 despite the rail strike difficulties that weekend. The Compass Eye was hanging in the Thames-side Gallery Studio Holders Showcase exhibition. Thank you to everyone who came to visit and found their way to my studio, it was great to discuss everything from Plato to Planck.

Super happy to have my video Cosmic Chiasmus: crossing the universe included in the May Fair Showreel screening at the very smart May Fair Theatre as part of Mayfair Art Weekend. The departure point for the curated selection was the word ‘PROCESS’, which was inspired by the video work by Wolf Vostell, Auto-Faber (1973). It was a great experience to see all the amazing nominated films and meet the selectors -Elisa Tosoni, Angel Leung and Eugene Macki and art weekend project manager Cheri Silver.

What a lovely write up in the Winchester School of Art Yearbook 2022 from one of the Fine Art students on the Images In The Making sessions that I ran.

I am delighted that my installation The Forms has been selected for exhibition in the splendid Wells Cathedral as part of Wells Art Contemporary 2022.

Twelve aluminium plates in the shape of pentagons that together make up the net of a dodecahedron have been deep etched with imagery taken from data visualisation of dark matter provided to me by KIPAC, Stanford University. The etching process used a screen printed sugar lift technique where the bite was allowed to penetrate completely through the plate leaving holes in some areas.

Excited to be selected for a satellite exhibition at the international print conference IMPACT12 to be installed at a former police station in Bristol. At a distance will be shown in The Anxiety of Interdisciplinarity, an exhibition which seeks to reframe printmaking as a site of interdisciplinarity – a testing ground for ‘The important work…done at the surfaces between adjacent disciplines’ (Carter, 1998).

Drawing on the physical language of print that embodies touch, separation and mirroring the semaphore flags in this work have been printed using hand painted dye sublimation inks applied via a heat press. This process transfers the ink from a paper matrix onto the substrate textile. The image passes momentarily across space in a dematerialized state as vapour before being reformed as its mirror opposite.

Billed as an immersive experience like no other Dreamachine offers a unique journey into the potential of your mind. Stimulated by strobe lighting playing rhythms on your eyelids and spatial sound fed directly into your ears, your mind creates its own images behind closed eyes. Inspired by a 1959 invention from artist–inventor Brion Gysin it has been reimagined by Collective Act, in collaboration with Turner Prize-winning artists Assemble, Grammy and Mercury nominated composer Jon Hopkins, and a team of leading technologists, scientists and philosophers.

It was pretty amazing. From a deep orange glow of swirling matter kaleidoscopic shapes emerge with geometric patterns that form and explode into vibrant pulsating honeycomb structures. Felt sure I was seeing some of my recent work in there. Swept away on a tide of colour with a big smile it was like a roller coaster ride through the forming of a technicolour universe. Wonderful.

Interesting to read that the frequency range of light emitted by Brion Gysin’s Dream Machine corresponds to alpha waves, electrical oscillations normally present in the human brain while relaxing. The pulsating light stimulates the optical nerve and alters the brain’s electrical oscillations. I have been looking at scientific research that explores a connection between the Earth’s magnetic field and human vision when stimulated by blue or polarised light depending on the orientation of the viewer. The human brain’s alpha waves can be seen to react to the local geomagnetic field. Some research correlates the nature of our dreams to magnetic field activity with calmer dreams resulting from high activity and more bizarre dreams when activity is low.

Going from Dreamachine to Libby Heaney’s quantum world of morphing fluid shapeshifting worlds The Evolution of Ent @Arebyte was a nice continuation of mind bending immersion.

Ent-er. Ent-anglements. Ent-ropy. Ent-wining. Ent- hralling. Ent-icing.

Looking at the potential futures created by quantum computing where the digital mode of binary gives way to superposition and quantum entanglement. Daniel Cavalcanti has provided a useful quantum glossary in the exhibition catalogue. Explaining superposition as like looking through a window and seeing outside and yourself reflected simultaneously, two configurations happening at the same time.

I was very excited to visit The World of Stonehenge at The British Museum to see the Nebra Sky Disc, having been introduced to the existence of this amazing object by archaeoastronomer Carolyn Kennett while on the Lizard Point Residency in 2019. Found by metal detectorists in Germany the gold used in this ancient map of the cosmos can be traced to Cornwall.

Carolyn explaining the history of this most ancient of cosmological objects.

The actual disc was much larger than I expected and almost translucently thin.

Six thousand years ago in the final 1,500 years of the stone age was the British Neolithic period. A time of stone axes for chopping. Woodlands cleared for farming. Stone held meaning. Offerings were made to spirits. Hundreds of stone and wooden circles were raised across the land. A cosmic inversion, connecting earth to sky. The first stones were brought to Stonehenge about 5000 years ago to create a burial ground which was transformed 500 years later into the symbolic site where the large sarsen stones were placed in alignment with the sun as it rises at midsummer solstice and sets in midwinter. Some astonishing objects in the exhibition, the power of the sun celebrated and reflected in gold.

I had high hopes for Our Time on Earth exhibition in the Barbican Curve – the aim was for technology to bring us closer to nature and highlight our place as one species among millions of others, striving to live together in a delicate balance. There was some enticing imagery and interesting ideas but as an experience it was tech overload, information overload all crammed into quite a tight space. Too much to take in and too removed from a lived time on Earth for me to engage and absorb anything meaningful.

Postwar Modern at the Barbican Gallery explores the art produced in Britain between 1945 and 1965 in the wake of a cataclysmic war. Including; Denis Williams Painting in Six Related Rhythms 1954; Eduardo Paolozzi Will Man Outgrow The Earth? collage form the series Bunk 1952/1971; the lovely Aphra Shemza’s grandfather Anwar Jalal Shemza painting fusing Western ideas of abstraction with Eastern influence and Gustav Metzger Liquid Crystal Environment  made using heat-sensitive liquid crystals that are placed between glass slides and inserted into projectors where they are are rotated to create movement within the liquid causing the crystals to change colour as they are heated and cooled.

I was fascinated to learn about the numbering system used by Cistercian Monks while visiting the impressive ruins of 12th century Cleeve Abbey in Somerset. A single cypher can represent numbers up to 9999.

The abbey church was destroyed by Henry VIII during the dissolution in 1536 but the cloister buildings, gatehouse, 15th century refectory and 13th century heraldic tiles survived destruction as they were being used as farm buildings at the time and it’s ancient tiled floor was protected from the elements by a cabbage field.

Sensory overload on the Lizard Point Artist Residency hosted by Mayes Creative and Lumen London. Serpentine rocks, wide horizons, sparkling sea, dark starry skies swept by the dazzling beam of Lizard Lighthouse.

We are here to research the communication heritage of this dramatic coastline once plagued by shipwrecks and pirates.

Rachel Holder from the National Trust guided us along the cliff path and told stories of the treacherous seas and lives lost on the hidden rocks. We heard about the history of Lizard Lighthouse and other methods of communication across distances.

We visited Marconi’s radio station hut which was full of wonderful scientific equipment like spark transmitters and Morse code machines. In the early 1890s, Marconi began working on the transmission of telegraph messages without connecting wires. An early experiment was a storm alarm made up of a battery, a coherer (an early form of radio detector consisting of a glass tube loosely filled with metal filings whose bulk electrical resistance decreased in the presence of radio waves), and an electric bell, which went off when it picked up the radio waves generated by lightning.

The message ‘WE ARE ONE’ was filmed on 29th March {non} Brexit Day signing with entanglement semaphore flags across the ocean

The plan is to make a film exploring communication across distances, relating it to entanglement theory where two paired electrons mirror each other. This will then be back projected onto a frosted Fresnel lens as used by lighthouses.

Joanna Mayes gave us a warm welcome to Cornwall on arrival as we witnessed the molten sun colour the whole sky before dropping out of sight.

1903 sunset

Sitting in the receding warm glow of the sunset we listened to the electromagnetic musical collaboration between sound artist Justin Wiggan and some house plants.

The meteor viewing pod created by artists Andrew Bird and Christina Romero-Cross was installed in the YHA grounds where a series of Deep Time films commissioned by Mayes Creative were screened with the sequence to be controlled by a cosmic ray detector.

The Sky Disc of Nebra is a Bronze-age astronomical disc possibly used to determine the seasons for sowing and harvesting in the Halle area of Saxony-Anhalt, Germany. It is the oldest depiction of the cosmos yet known from anywhere in the world. It was discovered in 1999 by metal detectorists working illegally who sold it onto the black market where  it was later recovered in a police sting operation. Analysis shows the gold and tin used in the disk were from the Carnon Valley in Cornwall. Evidence of ancient links between communities.

Workshops during the residency included looking at found matter under the microscope

A Chemigram workshop which involves painting various resist materials such as toothpaste, suncream and honey onto photographic paper before exposing to sunlight, fixing and developing.


Astrophotography; learning the camera settings to use to capture the extraordinarily starry night sky we were fortunate to experience. This shot was using bulb mode, focus infinity, 2.8 aperture, 3200 ISO, 30 sec exposure.

We did have to try and escape the sweeping beam of the Lizard Lighthouse but for some shots the added exposure gave some interesting results.

On the trip down to join the art and science Lizard Point artist residency we found ourselves serendipitously having a delicious afternoon tea at The Cornubian Arts & Science Trust (CAST)

The original Science and Art School was built in 1897 by Cornish philanthropist John Passmore Edwards at the request of local people.

The disperse papers left over from making the entanglement semaphore flags have good wormhole portal potential

Two great resources discovered:

Design Me print studio where I have tracked down a large format heat press available for open access.

Fat Llama a rental resource for practically anything and everything.

I rented an EF 100 f2.8 USM macro lens and set up a mini green screen in the studio. Apparently black tourmaline is good at cleansing negative energy so I sourced a pendant to use to create a hypnotic state of relaxation encouraging the release of negative energy to power the transformation wormhole. Have changed the chain to leather thong.

Not sure what the backdrop will be yet. Also tested the movement of iron filings against the green screen.

I made a frozen ice disk and tested back projecting particle trails onto it. This was tricky to film as rather slippy but I can see this could be a good effect showing the detail in the ice.

Tested filming the cloud chamber with the macro lens and although the depth of field maybe better because it’s such a small area in the viewfinder I didn’t capture many trails.

I’m not sure the result was better.

Got some good air turbulence though

I made a site visit in heavy rain to Salisbury Arts Centre

I will be installing Pentacoronae hanging sculpture for the Insatiable Mind exhibition as part of Salisbury International Festival.

It was great to meet everyone and hear about their ambitions for the space. Being an old Church the ceilings are very high. It’s going to be a challenge but they do have their own cherrypicker.

In preparation for the launch of the high altitude balloon with a cloud chamber in the payload students from Imperial College Space Society experimented with the mini DIY Cloud Chamber kits I provided.

1903 testing mini chamber 2

They are testing outcomes to design a prototype chamber that can withstand low pressure at high altitude, also they must ensure the base plate is kept extremely cold to create the supersaturated environment but any batteries onboard are kept warm enough to function and that turbulence doesn’t cause a whirlpool effect in the cloud.

It looks like we might be launching from an airfield near Oxford.

The New Materialisms Reading Group I attend are currently reading Scale. Geoffrey West’s research centres on a quest to find unifying principles and patterns connecting everything, from cells and ecosystems to cities, social networks and businesses. Full of interesting facts about heartbeats and energy, lifespans and growth cycles.

1903 tree rings

It has been alarming to read about the terrifying unpredictable phenomenon of exponential growth. At the beginning growth is slow, but this soon accelerates to such a rate that it becomes out of control, unstoppable and then collapses under its own weight.

I am also still trying to understand entropy as explained by Carlo Rovelli in The Order of Time. So, the universe began with low entropy and it has been increasing ever since, the past leaves traces in the present caused by the irreversible process of energy degrading into heat from which our brains create extensive maps of past events and this is what gives us the sensation of time passing.

Fun night with Andy Holden at The Cinema Museum.

Laws of Motion in a Cartoon Landscape uses live green screen filming allowing the narrator to interact with clips from hundreds of cartoons. The film proposes the world is best understood as a cartoon through examining the formation of ‘laws’ within cartoons as a way of making sense of the world we inhabit, a space where anything could potentially happen.

I joined some students from Imperial College Space Society and other High Altitude Balloon enthusiasts at Wormwood Scrubs for the launch of a couple of Pico balloons that they are testing tracking with the aim of making a complete circuit of Earth.

1903 pico launch 1

Anxious moments as the balloon barely gains height but soon it has vanished from sight

1903 pico launch

The next couple of hours are spent listening in for the tracker system transmissions which can drop in and out of range; travelling at something like 60metres/second both balloons made it to Belgium before the transmissions ceased.

Work resulting from an unexpected encounter that demands attention in By The Way at Lewisham Art House had some ephemeral photopolymer etchings of found seashore plastic by Sam Hodge.

I also liked this work by Mark Sowden who photographed found frames and then mounts the resulting image in the frame.

Great show Undertow at Sluice HQ. When prevailing discourses tip towards hyperbole, generalisations or simplification, there is a need to swim against the current, to carve out a space that allows for ambiguity, correspondence and a quieter voice. In the employment of few words, a scale of action or use of minimal materials, understatement can be both a way of confronting moments of crisis, or of evading them.

Time Tries All Things video installation at the Institute of Physics by Grace Weir explored time and our human relationship with it.

1903 Grace Weir Time Tries All Things

Two narrators consider time from different perspectives against the backdrop of a stone carver replicating a plaque, repeating time.

DAVID:
I think when people talk about time they often confuse two sorts of thing.
There is time itself and there is what’s called the arrow of time, which is
direction, and its perceived nature as a human being.

FAY:
Being or becoming is an ancient question.
Ever since we have records of people thinking about the world, in ancient
Greek philosophy for example, there have been people on both sides of
this debate.

The complete audio transcript is available here.

There is a very impressive diffusion Cloud Chamber in the foyer at The Institute of Physics. Lots of activity but it was hard to see the particle trails clearly through all the reflections. 1903 Diffusion cloud chamber

They also have a cosmic ray detector on the roof which has scintillator plates containing molecules of a substance which emit a tiny flash of light when they are hit by a high-energy particle.
