Coat Rack Wall Stickers and Hook
I saw this in Dwell about a year ago and thoughtit was the awesomest thing ever. The main decal is a life size coat rack, with accessories you can place wherever you want. The coolest thing is the actual coat hook that comes with it, so it looks like you're hanging you clothes on the decal. This one from domestic.fr costs about $100 (USD), but after extensive searching found a really similar one on ebay for under $30!
