Explore twelve creatures and forms built from equations, in a WebGL 2 gallery: sponges with real cavities, a winged dragon, a sea star, a Fibonacci-spined urchin, a jellyfish, a hydra, an anemone, a perforated diatom, a radiolarian cage, branching coral and a logarithmic shell. Every slider rebuilds the geometry, each form opens its construction equations, and a cutaway plane and wireframe show how it is made. Runs offline.
