This is how toys entertain themselves when you're not around

Lego mad scientist Hans Andersson has built a sudoku-playing machine and a machine that solves Rubik’s cubes out of automated blocks. Now he has outdone himself with a working clock.

I have always been fascinated with time and clocks. Time Twister is my first clock invention… Time Twister consists of two LEGO Mindstorms bricks communicating via Bluetooth. The master brick keeps track of the time and handles the minute digits. The slave brick handles the hour digits and the second indicator.

Did I mention that some people have too much time on their hands?
