Vihart

""Let's say you're me and you're in math class...""

Vihart is a "recreational mathemusician" with a site and a Youtube channel. She really gained her fame when John Green discovered her as part of The Station Is Watching You, and has since gotten herself 96,072 subsribers on Youtube. As you could guess from her "job title," her videos center around math and a little music, as well as doodling.
