Conway's Game of Life, actually...

I dug the display board and the horizontal and vertical driver boards out of a box of junk to revive this long-dormant project.  I also realized I never documented the driver boards - I'll have to do that next.

Anyway, I had some fun tonight driving the display with an arduino nano instead of the FPGA I'll use for the oscilloscope mode.  Beyond the basic light every pixel and draw some diagonal lines, I wanted something interesting to watch, and this was the first thing to come to mind.
