As part of my Enki exhibition at Kapellica Gallery in Ljubljana 2012, I developed a related perceptual illusions and brain hacks workshop with Marc Dusseiller [Hackteria], as part of the gallery’s Biotech program. We came up with the idea to make a special issue circuit for the workshop and we set to work designing a circuit the encapsulated the Enki project in miniature.
After a couple late nights, we came up with this super cool PCB design. Marc worked hard to create a fully functional efficient design, which was also aesthetically pleasing. The outline of the fish is also the ground in the circuit. This has to be the most ultra minimal brain-machine available to build. 6 components. We spent further late nights acid etching the circuits for the workshop in Marc’s home lab.
It uses ‘biofeedback’ to control the pulse frequency of the lights, low tech Galvanic skin response. Your fingertips press on the fingerprint, acting like a simple resistance meter, sensing the sweat levels to control strobe frequency [specifically 10-30htz to create hallucinations] of two ultra-bright LEDs to create the optical stimulation. The capacitor and resistor set the standby slow pulse and the range within the level necessary to cause visual hallucination. The design incorporates measurement graduations for eye spacing so you can personalise LED placement to fit your eyes.
It’s possible to use extra LEDs and several colours. After soldering the 6 components its possible to layback and experience your own personal electronic psychedelic experience.
Shortly after my experience of the “Strange face in the mirror experiment” I made these drawings in low light conditions as a way of recording the perceivable elements of my face and shape of the head. The particles of carbon and graphite reflect well the visual noise, like static, one experiences in the experiment. These drawings don’t illustrate the hallucinations I experienced [these will follow]
For my description of my experience of the ‘strange face’, illusion see here… “staring at one’s own reflection in a mirror in a darkened room for some time can induce vivid hallucinations. For purposes of research, I had to try it” My experience of the ‘strange face illusion’…
James Turrell’s Light Reignfall @LACMA – Andrew van Baal
James Turrell’s Light Reignfall Light Reignfall is a work from his series of perceptual cells, inside the participant is exposed to a uniform homogenous field of modulated light. A combination of sensory overstimulation, yet deprived of recognisable forms or space, hallucinatory effects are experienced.
“Assisted by an attendant, an individual viewer enters a spherical chamber on a sliding bed. A program of saturated light (operated by a technician) surrounds the viewer for twelve minutes, allowing the visitor to experience the intense, multi-dimensional power of light and the complex seeing instrument of the human eye.”
“James Turrell (b. 1943, Los Angeles), a key artist in the Southern California Light and Space movement of the 1960s and 70s. The exhibition includes early geometric light projections, prints and drawings, installations exploring sensory deprivation and seemingly unmodulated fields of coloured light, and recent two-dimensional work with holograms. One section is devoted to the Turrell masterwork in process, Roden Crater, a site-specific intervention into the landscape just outside Flagstaff, Arizona, presented through models, plans, photographs, and films.”
