Karen most awesomely illustrated the scenario she described, with XKCD-style stick figure art.
Well, I exclaimed in comments. If she can do something so awesome, I can certainly do something half-arsed and attention-grabbing.
Some of this art will be done with mouse and Graphic Converter. (Think MS Paint.) Some will be done with stylus and MacBook Trackpad and Inklet—and GraphicConverter. Some will be done with my trusty LAMY safari pen. All will be devoid of perspective, chiaroscuro, detail, or any artistic sensibility.
