Designer Xuan Yu's clever Rethink hanger isn't a product on its own--the question-mark-looking gewgaw requires you to recycle, that is, to screw two empty plastic drink bottles into it, and then it becomes a coat hanger.

Money-grubbing hotel chains should use these in place of their anti-theft hangers; having a bunch of these hanging in the closet would require you to drain those $6 bottles of water in the mini-bar.
