Go back to your childhood and imagine the day you played with Lego.
Sweden-based programmer Hans Andersson created a digital clock out of LEGO.
Using two LEGO Mindstorms bricks that communicate through Bluetooth, Time Twister changes time through brick layers.
The brick layers are laid out in different patterns and can rotate 360 degrees.
When the time changes, the clock takes approximately 30 seconds to adjust the layers for the desired digits to be displayed.
