Christmas Eve Sand Drawing

I drew this 80-foot (25-meter) design on a cold Christmas Eve.

Here are my neighbor’s four adorable children standing in the center, after their two dogs ran amok through my design five minutes after I completed it.

Beauty is ephemeral. Beauty is eternal.

I drew a 100-foot (30-meter) pattern in the low-tide sand. No calculations; no measurements; no eye-balling; no trial-and-error. It’s a self-consistent Euclidean, or straight-edge and compass, construction. The only tools used were string, two stakes, and a rake. What Euclidean constructions are possible is described by a branch of mathematics called Galois theory. The two figures, providing a sense of scale, are surfers.
