Dice value readout using Arduino AVR

How cool would it be to make your own true hardware random number generator? With this dice scanner we are already half way through.

This device consists of 5 IR pairs (transmitter+receiver) which are positioned under the dice. Although there are 9 possible pip positions, the value is read out by scanning only 5 of them. The brain of this thing is an Atmel Arduino and the read value is displayed on a 7-segment LED display.
