Brion Gysin's Dreamachine is a unique and innovative device that explores the boundaries of the human mind and perception. As described by author J.G. Ballard, "the Dreamachine is the first totally art-created hallucination-machine, producing effects similar to those of the surrealist décor and to the effects of mescaline." The Dreamachine is a stroboscopic flicker device that uses a rotating cylinder with slits cut into it, creating a strobe-like effect that is meant to be viewed with closed eyes.
