Mockup of main game screen. I don't actually have code for displaying the cards yet. Somehow I need to split my image into several smaller ones to have an UIImage for each. The big image will be 2MB in memory. An older iPod touch has 128MB of RAM so doesn't seem like an issue. Documentation did warn about having visible images larger than 1024 x 1024 (OpenGL thing I guess), which my image is. But I'm not attempting to display it all at once.
