Wake Up Alarm Clock

The Stonhenge-inspired Wake Up Alarm Clock “uses a simple robot arm to re-arrange a set of 14 numbered cards that indicate the current time.” Video after the break.

The name comes from the fact that the cards are arranged in a semi-circle around the arm so that the software can easily keep track of where they are. The cards are made from simple foam-core but also feature a set of neodymium magnets on the bottom that stick to metal screws around the base.
