Last month I wrote about self-titled "Mathemusician" Vi Hart and her wonderful doodle drawing videos that are as entertaining as they are educational-- not an easy thing to pull off.

 

Her latest video is a smart and informative look at spirals, the fibonacci series, and the places where the series shows up in nature.

 

 

Check out the rest of Vi's videos on her YouTube channel.
