When Arcade Game Creatures Attack!

So imagine this: You've got some kind of handheld inviso-detecter-o-rama and through the viewfinder you can see the invisible creatures in your world. Better yet, if you can see them, you can shoot them. Now imagine this handheld device looks an awful lot like your Treo.

ToySpring has created a game, called Arcade Reality, using your Treo that uses the live image from your camera to to superimpose the creatures on. So it appears as if you are fighting arcade creatures in real life. Here are some more screenshots.

Personally, I don't see how they can get enough processing power out of these handhelds to do this, but the machine might have overlay capabilities that I'm not aware of (I've never tried to program a Palm like that). Or they might just be faster than I think. I have seen some zippy video games, I juse don't play them that much these days...
