More Hexaflexagons

Remember last week when we told you that we had been playing around with hexaflexagons here a Digital Diner?  Well, we were inspired by Vi Hart, who was inspired by other people who were inspired by Martin Gardener who was inspired by Richard Feynman and others.  I had no idea that hexaflexagons had such a long and distinguished history of inspiration. The good news is that Vi Hart is back with a new video to tell us a little more about hexaflexagons and a lot about mathematical inspiration.  Take a look and be inspired.
