LET ME TELL YOU WHY DAVID CERNY IS AN ABSOLUTE NUTCASE.
"Tower Babies" 2000.
"Svaty Vaclav (Sculpture)" 2006.
Born December 15th, 1967, David Cerny is a sculptor out of Prague. And he's insane. No, really. His sculptures are considered controversial and lewd (really they all just involve butts in some way or another, which is apparently pretty offensive in Prague). In fact, some of his work in 1991 (a vandalized Soviet tank) gained him the title "hooligan".
I like that his work is so mind-bogglingly bizarre and ridiculous, but still makes his viewers think. One of his sculptors is a butt. A literal giant butt with a lower body that you have to walk up a ladder and peek into the butthole to see the inside of it. A GIANT BUTT. Another one of his works is a kinetic sculpture with two dudes wielding their wieners and waving their streams of urine around (send a text message to them and they will write your message in their urine). He's an absolute nut, but I think he's one of sculpture's wildest geniuses.
