Pwehh!!, ... painters, photographers, digital manipulators, .. all calling yourselves "artists", ... all arguing about whose fingers do the most work!
Try doing some real art, ... dance ... the primal, first art, where ONLY your body is the instrument, using big muscle actions and complex coordinated motor tasks using ALL your anatomy, not just your puny fingers and hands. (^__^)
I think the video is really cool, by the way, .. all joking aside, and all concern for cost ignored.
