Escher Bracelet is the 88th xkcd comic.


The bracelet is in the shape of a Möbius strip, a loop with one twist in it so that the entire surface area of the strip is a single side. Escher created several drawings and woodcuts featuring Möbius strips as an interesting mathematical shape.

The phrase "What Would Escher Do?" is a reference to the "What Would Jesus Do?" clothing fad of the 1990s, in which Christians wore bracelets marked with WWJD as a reminder to follow Jesus' example in their actions.  Here, Randall apparently wants to emulate Escher, and creates a bracelet for that purpose.
