A good game to play with a bunch of people:
-Get a bottle of hand lotion
-Put an excessive amount on everyones hands
-Everyone gets in a close circle. Then you
start grabbing someone's wrist kinda tight
so that it slips out. It makes a real trippy
tight ball of hands. The harder you grab,
the tighter the ball gets. If you can going
real fast it gets really cool.

you could show like trippy slides of fractals and things and the people could all wear white and have fun walking in front of the projector so it looks like they are wearing the fractals
