Doodle Music by Vi Hart

From the ever-inspiring mathematician (and mathemusician) Vi Hart

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.
