Do any ios graphics libraries have built-in 'explosion' effects?

Question

Given a UIImage, I'd like to "explode" it into a bunch of little pieces as a cute animation. Letterpress has something like this. Any thoughts?

Answer 1

There is a library available to do this now. Its MIT licenced too. You can grab it here: https://github.com/vibrazy/letterpressexplosion

Answer 2

For 3D effects, you should use OpenGL.
