3D Digital LEGO Clock - Time Twister 4

Time Twister 4 is a digital clock built entirely out of LEGO bricks. It is powered by LEGO Mindstorms.
The clock display is made up of a matrix of cubes that can be pushed out to show the time.

Each digit is powered with a motor that drives a conveyor belt with small knobs arranged in patterns that affects a mechanism that pushes or retracts the cubes.
(The 10-hour digit is simpler since it only needs to show the digit 1 or no digit at all)
