Just
Friends non-totalistic rule with many interesting
patterns.
Rule
3/2ab3, another non-totalistic rule with small
gliders.
The Logic
Rule, yet another non-totalistic rule with small photons
and a nice replicator-based photon gun, allowing logic
circuits to be built from glider streams.
Triangular
cellular automata, Carter Bays. His rules 2,4/4,6 and
2,4,6/4,6, at least, can generate gliders from random initial
conditions.
