I spent majority of the time doing UI yet ran out of time and it still isn't clear what's happening. Oh, well :)
I'll try to explain what's going on.
First, the two pink squares with smaller squares inside on the right are dice (although with non-traditional patterns). The smaller squares inside them are pips. The two pink dice on the right are being combined to generate the color flipping pattern on the left. Suppose the two pink dice on the right are ## # # # Then the color flipping pattern will be # # # # # # I.e. each pip from the first pink dice will be replaced by the pattern of the right pink dice.
Hope this explanation is clear - though it probably isn't :)
