Companion Cube Speaker Box or a detailed model of a companion cube

This was initially done as an exemplar for my students, but I thought I would share it with the whole world.
For fans of Portal/Portal 2, this is intended to be a speaker box designed around the Companion Cube. The circuit kit for the speaker is not my own design but can be purchased from here http://www.designability.com.au/classroom-projects/stereo-ipod-dock and has evenything in the kit you need, minus the solder, soldering iron and music source.
The base cube is a 100mm cube.
