I'd like to see an iPad update that includes the ability to use the iPad camera "LIVE" whilst drawing on the canvas. Such that I can fix the iPad in position and the rear camera is pointing to my subject. Why do this when you can shoot a pic and add it as a trace or reference? No particular reason. However, if it can be done... it would be really cool. it would be like painting on glass. I think it offers interesting opportunities to explore.
