Design submitted by Peter from the UK.
This simple LED watch design may look cryptic at first until you look at it from a different perspective. But rather than move the watch to find the correct perspective, you move an element of the watch.
To see the time you first must start to rotate the bezel. This illuminates the LEDs that shine through holes in the disk on the front of the watch. The LEDs will appear random at first until you rotate the bezel further until the LEDs align with the correct holes in the disc and show the time.
