The photon/XOR system. — New! A one-dimensional CA-like system that generates a pseudorandom walk.
The 17c/45 Caterpillar spaceship.
Lightspeed signals in Life. — Updated August 2007. Lightspeed signals come in many forms. Read all about them.
Still lifes or pseudo-still-lifes? The smallest patterns that lie on the borderline.
Random Agar v1.1 (released October 2002). This program is intended to look for new Life oscillators, wicks, and agars. It generates random spatially periodic patterns, and runs them until they oscillate. It includes complete support for all possible symmetry types.
Catalyst v1.0 (released March 2001). This program finds ways of modifying the evolution of an input pattern by placing catalysts that react with it, by a backtracking search.
Stable and Glider (released February 2000). What if a glider collided with a group of simple still lifes, generating a glider in the opposite direction, and then the still lives re-appeared in their original configuration? While a little bit unlikely, such a reaction (or a couple of them) might lead to an arbitrarily-slow spaceship or a new stable glider reflector. With this program I tried systematically to find such a reaction, and I didn't find anything (although I didn't exhaust all the possibilities).
Still Lifes Auto (released August 2001). This program stabilizes still lifes heuristically. It's also useful for designing still lifes by hand.
Zig zag. Gliders from a rake are bounced back and forth forever by heavyweight flotillas that come out of an assembly of guns. June 1998.
