Brion Gysin and the Dream Machine

Brion Gysin was an artist, traveller, writer, and alchemist of the 20th century. He was a great friend of author William Burroughs, who used his cut-up technique. The cut up technique, which definitely shows some parallels to Dadaism, is a literary style in which text is cut up and rearranged to create a completely new text.

Bryon Gysin's Dreamachine is another one of his cool discoveries. The Dreamachine is simply a cylinder with slits on the slides, placed on a record turntable and rotated. The light bulb underneath the cylinder, illuminates through the slits and creates a visual stimuli. Behind closed eyes, the user will see all sorts of patterns, shapes, and colors, and might even enter a hypnagogic state. It can be pretty intense, but the experience is over as soon as the user opens their eyes.
