Using Stop Motion Animation in Math

So, I just couldn't help myself.  After posting this on Twitter earlier today: "I wonder how using stop motion animation could be used in a math class. I would love seeing some short videos on dev. math and calculus.", I decided to take a look around the web for what I could find out on my own.  This link from DreamBox Learning lists several resources from PBS that could be adapted for Developmental Math classes, and a link to a Stop Motion Works article.  Anyway, during my search, I found a few videos that I am sharing below.  Enjoy, and let the creativity begin.  And by the way, all of this started after reading an article about how to make your own playdough.
