Where do crazy yet inspired ideas go

While searching on Yahoo for "super mower", I ran across an interesting web site: www.halfbakery.com. It's place for people to put inventions and "good" ideas (for values of "good" ranging from clever to insightful to strange to funny). It's sort-of like the lazy web meets Tantalus. With ideas like the "Film Noir Home" and "Custard-Filled Speed Bumps" (Mmmm... Custard ...), how can you go wrong?
