visualization on ipod touch

visualization on ipod touch
IPod Nano 3G market and compatible with applications other than games?

I am interested in things like visualizations and other programs, but the iTunes Store appears to have only cases for iPhone and iPod Touch.

iPhone and iPod Touch are the only compatible. It would be difficult but it was a "Jailbreak" not found in principle, Stampfer, and you can use many features that even the touch iphone / get to be preserved. My friend is with 4GB and his touch and he likes it.
