Will, my grandson, got a 12,000 piece Lego set; seemed like 12,000. There were at least a dozen small cellophane packets with different parts inside. Will’s dad had the unenviable task of inventorying the parts as Will did his job as a 5-year old: undoing what his dad was doing. The sketch below is the combination of time-lapse, blind and sighted drawing techniques. Will was so excited, he couldn’t stay in one place. After one position-defining stroke of my pen, Will moved and I had to wait for him to return to that place before adding another line. His dad was easier to draw, since he was quite still, looking for the correct part to snap into place.
