my favorite always involved something i learned in jr high. and then twisted via my perverse imagination :P
supposedly we don't really see objects, we see the light they reflect. like plant reflects green light and absorbs the rest. so if we're seeing the light it reflects.. what color is it really? every color but green? white? clear?
so sight is all one big lie, as we aren't really seeing the object itself.
if nothing reflected any light what so ever, we wouldn't be able to percieve the difference between one thing, or the next, and would be running into walls constantly :P
