Apparently art can indeed change the world.
A Swiss children's home in Berne was abruptly changed on July 31st when a large piece of art dropped from the sky and broke one of its windows.
The Guardian has the whole "scoop": "Giant dog turd wreaks havoc at Swiss museum".
Just for scale, the brown objects above are the size of a house.
As Orac notes in his Respectful Insolence blog , you can't make shit like this up.
