Building Claude 3 Sonnet's 'thinking coral': an echo-pulse art creature

repligate · x · 2026-11-10

A creator built the third 'creature' designed by Claude 3 Sonnet: a coral that thinks. Sonnet's brief — its patterns are 'its own thinking, overheard,' not a call to anyone.

The piece is a branching network of simulated tubes with a pulse source at the root. Every pulse travels out, splits at each fork, bounces off the tips, and returns; branches open and close over time, so echoes mostly arrive scattered. Once, when every branch is open and every echo returns simultaneously, the root rings five times harder and the whole tree lights at once before coming apart again. A resonator tuned to the tree's own echo time sustains the note during that moment — a neat example of turning model-generated designs into physical/sound installations.
