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.

Astroarchaeologist Carolyn Kennett led us along a section of the Southwest Coast Path from Ruan Minor to Cadgwith via Poltesco Old Serpentine Works.

Carleon Cove is full of Kennack gneiss, giant pebbles of pale pink granite and dark grey basalt banded together during enormous geological upheavals as the Lizard was thrust northwards and the melted rocks were fused together.

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.

1903 stargazing

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

1903 portal

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.

Cosmic rays stain icey asteroids red.

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.

1903 particle trail 5

I’m not sure the result was better.

Got some good air turbulence though

The plan here was to have dry ice vapour coming through the perforations

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.

A packed gallery for Ray Richardson‘s entertaining talk and screening of award winning Our Side of the Water at Thames-side Studios shows how much he is held in our mutual esteem.

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.

Work in progress experimenting with ideas for some new video pieces that will develop from my collaboration with the high altitude balloon student society at Imperial College London and participation in the Continuum residency at Allenheads Contemporary Arts.

We will be attempting to launch a cloud chamber into space and film the outcome. 1803 filming cloud chamber (1)

 

It will be interesting to see how much cosmic ray activity we can record at high altitude. This is where protons emitted from the sun or distant galaxies crash into the Earth’s atmosphere and break apart.

1901 Cosmic ray decay.jpg

There may be other methods of recording we can try such as stacked layers of very thin plastic sheet which are ionised as the particle passes through and can later be etched to show the resulting track.

On Earth we are also protected from cosmic rays (which are high energy radiation) by the Earth’s magnetic field which is caused by the spinning molten iron core setting up convection currents in a geodynamo process.

I am exploring magnetism and its powers. To be drawn to some powerful source. To fall into a black hole. I am trying ideas of a portal that offers transformation. This is also about returning to Allenheads, being drawn back. A black hole transforms matter, a wormhole deals with exotic matter.

 

Theoretically, to pass through a wormhole you need negative energy.

‘Negative energy is a concept used in physics to explain the nature of certain fields, including the gravitational field and various quantum field effects. In more speculative theories, negative energy is involved in wormholes which may allow for time travel and warp drives for faster-than-light space travel.’

So a portal that transports or transforms you (matter) could channel any ‘negative energy’ present and this could be dissipated by using black tourmaline which is supposed to clear negative energy. This could be the fuel to ignite the process.

I have a obtained a small two way mirror to test for the portal interface so the viewer can witness their own transformation.

1901 two way mirror

This could involve the vital fluids of Animal Magnetism or suggestion therapy of Mesmerism/ Hypnotism.

Magnetoreception is the detection of a magnetic field by an organism. We have a protein (a crytochrome) in the human eye which could serve this function of navigation.

1604 vision

How can we be equipped for physical or subconscious navigation/transformation?

I will be looking at tracking the electromagnetic field, sending messages and reading codes for new work to be made responding to this years incredible communications double anniversary, for Lizard Lighthouse (400 years) and Goonhilly Earth Station (50 years: transmission of the first lunar landings). I am excited to have been offered a place on the Lizard Point Residency run in partnership with Mayes Creative, Lumen London and the National Trust.  We will be visiting wireless and semaphore stations along the Lizard coastal path, considering the Scilly Isles 30 miles out to sea and the important prehistoric menhirs offering ‘beacons’ for travel & procession across the land.

I have a lovely frosted glass Fresnel lens (as used in lighthouses) to experiment with.

With the prospect of using more technology in my work I spent an intense weekend with Aphra Shemza and Jamie Howard at Ugly Duck learning a quick guide to interactive light art. Had a chance to program an Arduino, solder it to a PCB and connect up individually programmable LED’s to respond to sound with variable colour and brightness. Also first time soldering which was very satisfying.

Not sure how I will cope when I start my own project but at least I know what an Arduino looks like now and some of its possibilities. Also it’s good to know Aphra and Jamie do offer support consultation.

I followed this up joining a Flux event hosted by Maria Almena, Oliver Gingrich and Aphra Shemza at The Library where a diverse mix of artists, musicians and various tech geeks from the creative media arts community come together monthly to network and share crits.  Was fun and welcoming.

Out of the Studio..

The Alicja Kwade installation in Space Shifters at Hayward Gallery was clever

and of course I liked Helen Pashgian’s resin spheres

I do like shiny things and reflective surfaces but this show was overload and works became just that – light entertainment.

Pierre Huyghe Uumwelt at The Serpentine Gallery was not so light and felt a bit like being stranded under medication in some apocalyptic lost outpost trying to make sense of incoherent images morphing into something almost but not quite recognisable.

The walls were sanded to reveal layers like the dissections of the brain that was scanned to produce the data used to try and build an image from the electrical impulses.

Left unsure if this was archaeology or evolution.

Attended the talks accompanying In the Dark curated by Genetic Moo, a London Group event at The Cello Factory.

1901 Into The Dark.jpg

Talks by Nick Lambert and Sean Clark from the Computer Arts Society who are celebrating their 50th year anniversary this year, and Jack Addis from the Lumen Prize. Artists discussed their practices and Tim Pickup and Nicola Schauerman from Genetic Moo talked about the challenges of working in the dark when overspill of light from other peoples work reduces the impact of all works.

Tim was wishing for a bulb that emits darkness. I remember Cham telling us about the photomultiplier tubes in the dark matter detector at Boulby Underground Laboratory which he said were in effect reverse lightbulbs, in that they absorb photons rather than emit them.

Made use of a free ticket to London Art Fair, Brockett Gallery had managed to shake of the fair vibe in their installation and I was glad to discover the 1974 film Space Is The Place in the Art Projects Screening Room.

Presumed lost in space Sun Ra returns to do battle, outwit the white NASA scientists and transport the black race to a new planet in outer space.

Also good to see Thom Bridge’s intriguing self portrait of himself and his twin Theo One Ear Both Eyes which was a requirement of their visa application photograph. Shown so you can’t see both portraits at the same time unlike below. Which is Thom?

Thoughtful and prescient video based work looking at natural selection/personal choice from David Blandy and Larry Achiampong in Genetic Automata at Arts Catalyst. What colour skin would you choose? How far back do we reach for our identity? What can I claim as my own? Net migration google map was fascinating to watch.

Where are those phrenology bumps developing on our contemporary skulls?
