Here's a gesture that threw me; a guy brushing dust off his suit. Sounds simple, but I had to do a lot of sketching before I came up with anything that even came close to suggesting the movement I was looking for. As a last resort, I was going to try for a "strobe" effect but I didn't want to overdo it and call more attention to the action than I needed to.
