We have feature quite a few cool clocks here at Geeky Gadgets, the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open source Arduino digital clock.
The DOTKLOK comes with a range of cool animations which have been inspired by classics like Pong, Tetris, PacMan and Space Invaders, and it also comes with 14 selectable time animations.
DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns such as Morse code and minimal analog clock faces.
If you want one of these cool DOTKLOK digital clocks, they are available for $149.95 each from Etsy.
