I worked at CTN last weekend in the East Tent. I had to opportunity to work crowd control at Gesture Drawing with Dave Pimentel and at some point my sketchbook came out from hiding. We did several 1 and 2 minute poses and ended with some 5 minutes.. He encouraged us to post them online, regardless of quality, so here are all of them, the good and the unintelligible.
First 6 are pretty normal for what I was doing before. After those he encouraged us to stop using a line of action and to make bold singular strokes we had to commit to once they were down.
