Recreational mathematics

Vihart's videos on mathematics are brilliant and a treat to watch.  Here are a few of my favorite ones:
  • This one is a great use of "fruit by the foot"
  • This is a great Origami proof of the Pythagoras theorem

  • The most innovative story I've seen:

  • This one is a fun binary hand dance for Pi 

  • and one of my favorite ones is this one on fractal fractions (reminded me of some of my schoolteachers who took great pleasure in unnecessarily complicating math)

Check out her posts.
