The Luft Balloon Clock is a wall clock (also includes a desk stand) that looks like a transparent mylar balloon. Available from Lox in orange and beige for $146 apiece, the clocks measure approximately 13″ round and operate on a single AA battery. Me? I operate on veins full of espresso or I don’t operate at all. “Even a broken clock is right twice a day.” Then I am right twice a day while my seconds hand just twitches in place.
