A bit of fun for a Friday - an impressive twist on lego functionality. Thanks to our sister site New Scientist for flagging this one. It's the work of one Hans Andersson who has developed the eye-catching Time Twister...

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.
Each digit is made up of five layers with black and white tiles layed out in different patterns. Each layer can rotate 360 degrees before it hooks to the next layer. By twisting the top layer back and forth in a specific pattern, you can arrange the layers so that the desired digit is displayed.
