if you want to see something that messes more with your optical percetion, check out the Yerba Beuna show, one peice by 3 people, (can't remmeber names)one guy named Ara think from lightningbolt and a mr.Weise and someother name.but look for a triangle of mirrors and a rear projection simple optics that constantly change. Stand there for a long time and take it in sober. it is probably the best thing i have seen in a really long time in this city at a museum.....
