Sure, the physical build itself looks great ... The cube itself is controlled with an Arduino Mega 2560. For each frame in memory, the Arduino reads and bit shifts 49 bytes of data for an encoded ...

It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ATMega8U2 instead of an FTDI USB to serial converter chip.
