Hmm, hay tom you could totaly make a version of this with that level of display http://www.youtube.com/watch?v=jNKgpAFOsa0
I was thinking the same thing.
I've seen versions of Pong out there in Minecraft as well but I think they were using Redstone mods to do it
I've also seen a tetris in MC. But I'd find it easier to do stuff like this in real electronics. MC's redstone stuff is such a pain to do anything of any complexity in (without the redpower stuff).
