Are CA really responsible for patterns on shells?
Contributions by: arjen@fwi.uva.nl (Arjen Schoneveld) Pawel Siwak The latest American Scientist (May-June 1995) has a cover story on 1-D CA patterns found on shells (such as Oliva porphyria and Cymbiola innexa Reeve). Try the following book by Hans Meinhardt: “The Algorithmic Beauty of Sea Shells” ISBN 3-540-67842-0 ISBN 0-387-57842-0 Springer Verlag, 1995 G.T.Herman, G.Rozenberg – Developmental Systems and Languages. North-Holland, 1975: In the book you’ll find may be the first biologically oriented applications of cellular automata. This study of synchronization aspects of growing filaments is very interesting. There are also some shell patterns in the book, firing squad synchronization problem description, French flag problem solution, and many other topics on cellular automata and their biological context.
