Generally, I don't consider radiators to be all that interesting (unless it is shaped like a Lego brick), but this coiled radiator design from Ciussai is definitely an exception. The metal wire tubing can be wound and stretched much like a garden hose, which gives it far more functionality than simply heating a room. For example: you can coil it around a bar to dry clothes or lay it on your bed to warm things up on a cold night. I don't know how safe all of this is, but I love the idea. And the best part is that it can actually be purchased from Ad Hoc—although pricing details are unknown.
