Vi Hart’s Mathematical, Musical Doodles [Video]

Musical/mathematical artist Vi Hart has put together a meditative and lovely video featuring math-inspired doodles and music. Parts of it sound like they could be in a yoga session, in a good way. It’s a nice way to zone out during your lunch break. After the jump, read Hart’s description.

From her YouTube description:

A visual and musical expression of mathematical symmetry groups. The transformations done to the video are equivalent to the transformations done to the notes.

These type of repeating patterns are called frieze patterns. A couple wallpaper groups are also represented.

Who knew graph paper could be so stimulating?
