'Gliders' in an artificial chemistry based on the Gray-Scott reaction diffusion system in a specific region of interest called U-Skate World (named for the shape of the fast glider with a 'u' shape) developed by Robert Munafo. A glider gallery for U-Skate World suggests a modular construction system for straightforward construction of new gliders. (The glider starting in the top left, "berrycup" was built for DiscoGliders).
