What am I supposed to do with all the stuff children produce?

A nice post (and forum) over at The Juggle today about what to do with the 'art' that children produce. You don't want to throw it out, but you don't really want to keep it. Do any of readers with older children actually look back at their pre-school daubs? (Picture: 'Darth Vader on a throne' by Owen, from the splendid Flickr Child's Art pool)
