My RepRap with Makerbot Thing-O-Matic generation 4 electronics, printing it's first object that is not a square box ;-)

Finally got time to shoot a video of the cube in sort-of-done state ...
A 5x5x5 Cube, controlled by an Arduino-core (Atmega328P). Two TLC5940 takes care of the 25 outputs, while 5 P-channel mosfets switch the layers.
MicroUSB connector on back edge for re-programming the animations and for power. A Nokia LiPo-battery has been grafted on, as an afterthought.
