10:15 PM - Definitely sick. STILL sick in fact. I've done about two hours of research and have a theory I'd like to try: Create a CCRenderTexture with a "pen" sprite. Use CCBezierBy actions to move that sprite around as rendering happens over a given period of time. We'll see how that works!
2:15 AM - Well, 4 hours later and I think I may have lines and circles coded. However, I don't see the drawing if I try to run the action sequence, so either my actions don't work like I am expecting or my coordinates are way off. If I comment out the actions I do get to see my pen dot show up on screen. That's got to count for something right? =) More tomorrow.
