Sea Urchin Large

Dozens of spines, all heading somewhere else at once.

This large sea urchin by Oly is cast resin, a sculpture modeled on the natural specimen. Sea urchins have fascinated naturalists and collectors for centuries, their radial symmetry a tidy lesson in geometry from the sea floor. Here long tapering spines burst out in every direction from a small central core, some slender as needles, others broad at the base. The whole thing is a chalky matte white, which leaves the shadows between the spines to do much of the work. It is 24 inches in diameter.

Best admired, and not stepped on.
