I was playing with Python and PIL (Python Imaging Library) and came up with idea that I could make my own Lego Bionicle Random Symbol Generator. It's pretty much easy you have 4x8 tiles, pick color randomly put pixels randomly on 4x8 tile do the mirroring so it becomes 8x8 and viola that's it. I am not sure that's the right way to do it but some logic tells me it's close enough.
