Created by Brion Gysin and Ian Sommerville in 1959, the dream machine (dreamachine) is essentially a flickering light that pulses at 8-10 times a second. The original dream machine was created as a cylinder with slits sitting on top of a turn table. A light was housed inside and the slits were cut precisely to produce the right flickering effect. Against closed eyelids, the flicker causes the brain to submerge into a dream like state and produces an interesting effect of patterns and imagery. As with all flickering lights, it can cause photosensitive epilepsy in certain people. Check out the online dreamachine and how to build one yourself. There is also a documentary!
