I can't draw

OK, I'll bite. The SketchAR app provides a framework in which you can "learn" to draw - or at least trace a sketched-out version of one of your photos using a VR interface. It's a great idea, and I'm going to try it, as soon as I figure out how to hold the phone and the paper and the charcoal at the same time, while looking both at the phone and the paper.
