The movie is excellent. Its a total trip. I own it. Psychedelic masterpiece.
The movie is based on John Lilly. A very interesting author. The quote on my sig is from him LOL
His book "Programming and Metaprogramming in the Human Biocomputer" is kinda amazing. About getting over your hangups and negative programming through psychedelic drug use with ritualized intention behind it.
Along the lines of Leary's "Neuropolitics" and such, but much much deeper.
John Lilly invented the tanks. And figured out that dolphins communicated and could understand human beings.
