A friend was showing of his phone (I think it was a Nexus one), and the background was active (not just a image). It had waves going through it even while the phone was idle. Does anyone know what this is called, or if it will be on the Evo?

Its called a live wallpaper. It should come with Android 2.1 systems if not they will be on the Evolution rom!

my wife has that on her incredible. I'm pretty sure its part of the sense ui.

Ya, a buddy of mine has a live wallpaper on his phone, they are pretty sweet! Looking forward to the rom!!

In the android app market there is a koi fish pond wallpaper for the evo. I downloaded it and it works great. Shows fish swimming around and you can put how many fish you want.

Currently using "Starfield" - stars flying towards the screen; double tap for warp speed!

Can anyone provide link(s) for college football themes/wallpapers?

Im currently using the custom live wallpaper found in Bugless Beast Vol. 3

I currently use the unfortunately named Cuntface Live Wallpaper as my background. It reminds me of those silly GIF animations you'd see in forums.

Mario Live Wallpaper is up in the marketplace
