This is a video of the Dream Machine Brion Gysin and Ian Summerville invented and build after reading William Grey Walter‘s book, The Living Brain. It is a nice diy approach to making mechanical interfaces for psychedelic experiences and experiments widely available.
I hope to write a whole post on mechanical interfaces for conciousness manipulation (compared to chemical interfaces like psychoactive substances) soon.
You can find a java based online version of the dream machine here.
