With Javascript enabled you would be able to view the following examples of cellular automata rules: Superfluidity cellular automata rule Fluidity cellular automata rule Pops cellular automata rule Axels cellular automata rule Three State Extenders cellular automata rule Three State Extenders 2 cellular automata rule Three State Extenders Mix cellular automata rule SB16 cellular automata rule SB19 cellular automata rule SB31 cellular automata rule The rules here have sat around collecting dust for months, so I decided to make an exhibit out of them.
Some cellular automata rules are suitable for creating formations which appear to be fluid-like. Usually portions of these formations are unmoving and anchored. In rules which exhibit Superfluidity the anchors appear to stop and start moving for unknown reasons. I first saw examples of Superfluidity when exploring hexagonal cellular automata rule space for Collidoscope, where such rules are part of the Fingerprints family of rules.
The Pops Rule and the Axels rule are combination rules whose only difference is the respective mix ratios, which are 8:1 and 8:3 respectively.
The Extenders family of rules also has a hexagonal analog: Hextenders. The Extenders here are three state Extenders. The August Addition has examples of four and five state Extenders.
