I'm wanting to give my model in my live wallpaper some animations. How I have it set up now, It's spins around my model. What I want to do is, have it pan left and right, and when you touch the screen, it animates my model. Here are some references of what I'm doing, and what I'm wanting to do.

My own app
3D Jelly Bean Live Wallpaper
Jelly Bean 3D Live Wallpaper - YouTube

What I'm trying to do
Amazing Spider-Man 3D Live WP

minus the soundboard and widgets.
