# Halftone Caustic Spindle

A hollow lens filled with a halftone lattice of light dots, fringed with hair-thin rim rays and pierced by a dotted axis. The lens is one superellipse under six interpolated numbers, so it morphs by deforming, not cross-fading, through four forms: fat caustic pod, wide astroid lens, tall spindle, four-point caustic star. Bass swells it into a flat pod, treble opens it into a four-point star, and the dot lattice turns over as a wave running outward from the hollow. Rests as the astroid lens.
