I recently found out about an interesting art project, the R. Mutt sticker project. It is an ongoing project meant to advance the question asked by Duchamp himself when he placed a fake signature upon a urinal and tried to submit it for an art show, "What is art?" Even after his death Duchamp's moniker can be added to every day items in order to turn them into "ready made" pieces of Dada art. I found this image on flickr, but found no purchasing information for the clear format. I did, however, find a site that will send you a similar sticker if you send them a picture of the toilet you stick it to. I like the concept.
