Dude...check installer.app for a game called iPac3d. I have it on my iPhone right now.

The movement, accelerometer graphics, dungeon maze, etc are all almost identical to what we see in this video demo of Quake 3. The only thing that seems at all difficult is the actual multiplayer aspect of that, and given the hackers have already gotten all kinds of networking applications to work, it's no stretch to think they can't send some packets back and forth, is it?

I doubt this will show on installer.app, but show up first day in the iTunes App store when it opens for business? Pretty good chance, don't you think?

P.S. I don't care for the accelerometer based movement control; but I'm an old fart whose hand eye coordination isn't what it used to be.
