A Clojurescript implementation of the Wator simulation, as described in The Armchair Universe, by A. K. Dwedney.
Download from Github. You'll need everthing under the resources directory, which you should copy to an appropriate location (or web server) and change as required by the environment.
A. K. Dwedney's original paper can be found here.
The only real difference between this version and the original is that fish and sharks can move/hunt diagonally as well as orthogonally.
Try it at hydrus.
Probably many and various.
