From Sumi Ink Club a couple of weekends ago. I’ve attended the very beginnings of one before, but was unable to stick around. Interesting take on collaborative drawing. Ink only, no text, move around draw into other drawings. Not sure the reason behind the rules, but it does bring out some uniformity in the work. With a very mixed bag of people and ages interesting to see how outline and white space are the norm. I will post some Drink and Draw works soon to give some contrast in approaches to drawing games. 
Unfortunately, I was unable to stay for this event, but friends of mine took part the other night. If you haven’t heard of Sumi Ink Club, you can see what they do and the rules they abide by here. Another take on drawing games.
