These long, lightweight architectural drop earrings feature a precise diagram of the “Y-Combinator,” a famous logic structure that describes the mathematical concept of recursion.

Recursion is the idea of a process that refers back to itself in order to continue or repeat, like a mirror reflecting a mirror. In the world of logic, the Y-Combinator is the specific “code” that makes recursion possible. The geometry on these earrings maps out that logic.
