Interaction Design Institute Ivrea students Didier Hilhorst and Nicholas Zambetti 's Quattro alarm clock is housed in a translucent enclosure without button nor markings. Its functions depends on its position: orientating it on the side it's a radio, upright it becomes an alarm timer and placed horizontally it's a clock. As you come nearer to Quattro, it detects your presence and reveals illuminated touch-sensitive controls relevant to its current function.
There's more! The radio alarm works in tandem with a teddy bear: squeezing the bear triggers various actions including a remote "snooze" operation. (seen at the Strangely Familiar exhibition.)
