comment Smooth animation in Cocos2d for iOS
Definitely a good idea. However calling scheduleUpdate instead of schedule:interval: worked much better.

comment Skipping glReadPixels and reading iPhone's “VRAM” directly
Cool. What do you think about reading piecewise into a GLubyte buffer with glReadPixels... then dump the buffer to disk on another thread? The buffer would be alloc'd once and re-used. Suppose I might need two buffers since I'll be filling one while dumping the contents of the other to disk.

raw FBO dumps sound interesting. Formatting the data later will work. How would one save the contents of an FBO to disk?
