Want to create an app where a child would trace a letter with their finger as they learn to write the letter. I would show a letter on the screen say "b" and at the top of the "b" there would be a small arrow which the child drags top to bottom and along the curve on the right. As the tracing occurs, the color of the letter changes fro...

I'm working on an iPhone App that relies heavily on OpenGL. Right now it runs a bit slow on the iPhone 3G, but looks snappy on the new 32G iPod Touch. I assume this is hardware related. Anyway, I want to get the iPhone performance to resemble the iPod Touch performance. I believe I'm doing a lot of things sub-optimally in OpenGL and ...
