about the cover: Marius Watz is a distinguished digital artist whose bold abstract compositions are created directly through computer code. His tool of choice is Processing, a language built on Java and intended for use by artists and designers. As a student of computer science in the early 1990s, Watz would peruse Communications of the ACM at his university’s library, looking for articles on computer graphics. With this cover illustration, one might say a circle has been completed.
