For Movember I along with Alan Tew, Brandon Dayton, and Geoff SHupe, drew on a wall of a great grilled cheese sandwich restaurant called the Melty Way. All money made there that day went to Movember which is a fundraiser for Prostate cancers.
Had a great time, hard to draw large, vertical, and with no pencil lines or pre-planning. But a lot of fun just winging it and draw whatever you want.
Really cool watching the time lapse video, it was 4 hours of drawing. Check it out.
