Dreamachine

The Dreamachine (a portmanteau of Dream Machine) is a stroboscopic flicker device that produces visual stimuli. Artist Brion Gysin and William S. Burroughs' "systems adviser" Ian Sommerville created the Dreamachine after reading William Grey Walter's book, The Living Brain.[1][2]

History

In its original form, a Dreamachine is made from a cylinder with regularly spaced shapes cut out of its sides. That cylinder is then placed upon a record turntable and rotated, depending on the scale, at either 78 or 45 revolutions per minute. A light bulb is suspended in the center of the cylinder with the rotation speed making light emanate from the holes at a consistently pulsating frequency range of 8 – 13 flickers per second. It is meant to be looked at through closed eyelids, upon which moving yantra-like mandala visual patterns emerge, and an alpha wave mental state is induced. The frequency of the pulsations correspond to the electrical oscillations normally present in the human brain while relaxing.[2] In 1996, the Los Angeles Times deemed David Woodard's iteration of the Dreamachine "the most interesting object" in Burroughs' major visual retrospective Ports of Entry at LACMA.[3][4] The Dreamachine is the subject of the National Film Board of Canada 2008 feature documentary film FLicKeR by Nik Sheehan.[5]

Use

A Dreamachine is "viewed" with the eyes closed: the pulsating light stimulates the optic nerve and thus alters the brain's electrical oscillations. As users adjust to the experience, they see increasingly complex animated yantra-like patterns of color behind their closed eyelids (similar effects may be seen when travelling as a passenger in a car or bus; close your eyes as the vehicle passes through the flickering shadows cast by regularly spaced roadside trees, streetlights or tunnel striplights—these were the hypnagogic effects Brion Gysin said he sought to recreate with the device). It is claimed that by using a Dreamachine meditatively, users enter an alphawave, or hypnagogic state.[6] This experience may sometimes be quite intense, but to escape from it, one needs only to open one's eyes.[1] The Dreamachine may be dangerous for persons with photosensitive epilepsy or other nervous disorders. It is thought that one out of 10,000 adults will experience a seizure while viewing the device; about twice as many children will have a similar ill effect.[7]
