Ok, this qualifies as nifty.

Per Kotaku, id Software’s John Carmack demonstrated Rage on the iPhone 4 handset at QuakeCon 2010. The title, which ran at 60 frames-per-second, allowed Carmack to “kill anything done on the Xbox or PlayStation 2.”

The demo incorported id’s Tech 5 engine and could easily run on the 3GS with the visuals rivaling anything from the PlayStation 2 and original Xbox.

The first Rage game for the iPhone will be a small “show-off” sort of title, with a larger game due out next year to coincide with the big game’s release.
