Design submitted by Laszlo from Hungary.
This concept watch design is based on images of Hungarian-French artist Victor Vasarely, famous for op-art, a style of visual art that makes use of optical illusions.
Straight forward to read when you understand the layout, the blue LEDs indicate the hours (2 and 1 hours), the green LEDs indicate 10 minute groups and 5 minute groups. The yellow LEDs indicate 1-1 minutes.
The shapes and patterns of the display are continued into the strap to create a bracelet effect.
