Vi Hart was so frustrated by her boring math courses in high school that she began doodling in class, sketching snakes and trees and infinite chains of shrinking elephants, instead of listening to the teacher droning on. Vi, who calls herself a “full-time recreational mathemusician,” has posted some of her doodles on YouTube. They’ve now been watched hundreds of thousands of times, and in the case of the elephants, more than a million. She, and her videos, are breathtakingly original.
