One-minute gesture drawing

Back in 2011 I made a short video about gesture drawing and uploaded it to YouTube. I had done it on a Mac and soon afterwards my Mac was stolen. A little while after that I realized the video needed editing but was unable to make the edits in Windows XP, so I withdrew it from YouTube until I could fix it. Only now, four years later, have I finally been able to edit it with MovieMaker in Windows 7. The edits were mainly cuts, and I added a few bits of explanatory text. So here it is belatedly. Hope someone gets something useful from it!
