If anyone likes looking at newbie code for stupid things, now is your chance. I'll happily take any tips, comments, or even derision. My biggest fear is to hear "There's nothing you can do about it--stuff takes time" to which I would respond, "Then how does Blizzard do it!? I know they are drawing more than 226 rectangles!"

At Blizzard, we render graphics with OpenGL, which is going to be a lot faster than anything you can do on the CPU :) I haven't looked at your code, but have you experimented with CoreAnimation at all? This would let you leverage the GPU for your drawing as well, which might help. _______________________________________________
