Hardware almost done

After a long time of deliberating, trial and error, and much argument and solder balls made, we finally have a working prototype of our screen. The specs of the screen are as follows:

45x45cm clear acrylic (which I sandpapered to test if it would aid in diffusing the light from the projector; we will replace the acrylic later on)
4x4x8 Infra-Red LEDs lining the screen
1.25V, 50mA per LED, connected in parallel
80cm distance from Wiimote to Screen
20.4cm distance from Wiimote to Groundzero
WiimoteTester (by Brian Peek) is the program we're using to test.
Mr Shiney Finger and Mr Silver Thumb are pieces of aluminium foil wrapped around a finger and thumb to reflect as much of the infra-red light as possible.
