This is a fish-shaped keychain. The dorsal body pattern was created using a reaction diffusion system, also known as a Turing pattern. A reaction diffusion system (RDS) generates patterns by reacting chemicals that diffuse through space and time. You can learn more about RDS at: https://en.wikipedia.org/wiki/Reaction%E2%80%93diffusion_system Turing patterns are a type of pattern generated by RDS, named after the mathematician who first described them.
