In preparations for the Pac-Man CE project, I wanted to get a good visual representation of where everything is layed out in Pac-Man arcade hardware. The result is this Processing Sketch. It's far from done, but it was a nice exercise to help visualize things.
It really is just a database visualization project. The current results (I won't say "end results" since I never finished it) are kinda neat to play with. It doesn't completely work properly, but it gives a good idea of where I was going with it.
