This bizarre cube is the Cryoscope Haptic Weathervane, created by Robb Godshaw of Syyn Labs. Basically its sole purpose is to provide another way to accurately determine the temperature outside, without attempting to decode degrees or heading outdoors. It has an Arduino processor inside which raises or lowers the temperature of the surface of the cube to the precise temperature of the outside air. Now you can decide what to wear just as easily as you can hit the snooze button from your bed! (via)
