saw a sort of "science club" flyer on campus one time that had alex grey artwork on it, which immediately caught my eye
It said the group would discuss topics such as 8C-brain model, alternate dimensions, the universe, psychoactives, time, the fractal nature of reality, consciousness, altered states, dreams, meditation ect ect; basically everything people wanted to discuss in their classes but couldn't..
Some amazing conversations were had and i met some lifelong friends, to say the least
You could do something like this, and/or hold films like other people have suggested.. Its a very safe and effective way to get some like-minded people together and have a fun time IMO
<Ringworm>hehehe, it's all fun and games till someone loses an "I"
