From the reviews: "This book contains a collection of articles on the theme of how to do computation with mobile objects or patterns in nonlinear media, as exemplified most vividly by collision-based computing. ... Each chapter in the book has its own list of references ... . This book is recommended for anyone looking for an introduction to the fascinating developing subject of collision-based computing on a non-trivial level."
