Flash mob video from 2013 Joint Meetings

The flash mob was a great success, with some small groups making and unknotting human knots, and then all the groups coming together to make a big connected sum. The big connected sum ended up being a single knot, rather than several links, as we discovered by passing a hand squeeze around. Check out the video, and then you can look forward to participating in some kind of flash mob again next year!
