We've seen so many innovative radiator designs lately, there must be a space heater renaissance underway. This Radiafleur starts out shaped like a piece of pie, and as you spread its seven ceramic petals, you get more heat.

There's never any doubt about what setting is in use, because the positions of the petals are immediately visible, even across the room. This unique design concept, adding visible precision to getting you warm, is indeed very cool. Sure beats those old metal monstrosities sitting there, heating things up while looking ugly.
