The Clever Hook sounds cool, but based on the design it looks like you’d have to mount it on the edge of a wall for it to be effective. What is it? A self grabbing hook. Place anything on it up to 40lbs and the weight of the object forces the hook to clamp down. The heavier the object the tighter the grasp. The housing is made of translucent arclyc housing so you can see it in action. Design Within Reach has them for $10 a pop.
