- excellular: Cellular Automata with Excel (github.com)
This spreadsheet contains two cellular automata: the classic elementary automata described by Stephen Wolfram in A New Kind of Science, and a 4-color totalistic automata described by Kenneth E. Perry in the December 1986 issue of BYTE magazine.

COMPUTER-GENERATED mathematical art is art created by pure mathematics as opposed to other forms of computer graphics. In this article, the mathematical entities are “one-dimensional cellular automata.” I have found their study exciting and astounding.

A small southern constellation invented by the Frenchman Nicolas Louis de Lacaille during his survey of the southern skies in 1751–52. Pyxis represents a magnetic compass as used by seamen. It is located near the stern of the ship Argo in the same area as the ship’s mast. Lacaille’s original depiction of it was published in 1756 under the French name la Boussole, and in the notes accompanying the chart he described it as ‘le Compas de mer’. On the second edition of his chart in 1763 Lacaille Latinized its name to Pixis Nautica (sic), which was subsequently shortened, with amended spelling, to just Pyxis.

- Cellular Automata (plato.standford.edu)
Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance).
