   How would I go about applying a perspective tranformation (just like in photoshop) to a sprite? Are there any cocos2d functions that I have missed, or would I use OpenGL | ES? If so, what calls? (Unfamiliar with OpenGL)

   If it helps, I want to skew (I remembered the word!) the sprite, but be able to rotate it. Say you held a CD in front of you, you are looking straight at the top of it. That is my sprite. Now rotate the CD so you are now looking at it in a 3D sort of way. Now rotate the CD about the center hole. That is what I want to be able to achieve.

   Maybe you're looking for the CCOrbitCamera action?

   Running that action on your sprite should get the effect I think you're looking for. Check out the sample projects (ActionsTest) that you can run from the main cocos2d download. There should be a demonstration.

   So the CCOrbitCamera looks like what I want, but I am being very dumb and can't figure out the values to make it do what I want.

   What would the values be for

   [CCOrbitCamera actionWithDuration:5 radius:r deltaRadius:dr angleZ:z deltaAngleZ:dz angleX:x deltaAngleX:dx];

   r = ?
   dr = ?
   z = ?
   dz = ?
   x = ?
   dx = ?
