Möbius Music Box

by Leslie Taylor

Click to enlarge images
A Möbius strip is a surface with only one side --  a loop with a half twist. In the chapter about topology in his book The Joy of X, Steven Strogatz writes about Vi Hart, a "full-time recreational mathemusician," who created this Möbius music box. The music box plays a melody Hart composed, and then plays back the same melody again--this time with all the notes inverted.
 
Video by Vihart. The arrangement is a theme from the Harry Potter Septet by Vi Hart.
