The Hanger. Ferran Lajara has this cool collection on their site called "Active Furniture," objects which try to keep users physically active by creating new relationships. My favorite? These cool mountain climbing posts you install on your walls.  They serve as both hooks for clothing, and a rock-climbing-esque wall in your house!  Awesome.  No word on where to actually buy this "wall kit" but maybe you could make your own version?
