Quarter Moon

A repeating pair of discs - one full, one crescent - set into a steady grid. Depending on how the eye lands on it, the pattern reads as moon phases passing across the sky, or as pure optical-art geometry from the 1960s.

Both readings are correct. The crescent is one of the oldest patterns in any culture, and full-and-crescent pairs show up in everything from medieval astronomical diagrams to mid-century textile design. Bridget Riley and the Op Art generation reached for the same shape because the disc, paired with its bitten-out twin, makes the surface vibrate.

At jewelry scale the pair tightens to a single pendant or earring. The field of moons collapses into one full disc and one crescent, sitting against each other in metal.
