"One day, in a rubbish heap, I found an old bicycle seat lying beside a rusted handlebar, and my mind instantly linked them together. I assembled these two objects, which everyone (then) recognized as a bull's head. The metamorphosis was accomplished, and I wish another metamorphosis would occur in the reverse sense. If my bull's head were thrown in a junk heap, perhaps one day some boy would say, 'Here's something that would make a good handlebar for my bicycle!"
Pablo Picasso, artist 1881-1973
