Cassini Éditions Scientifiques, a French publisher of books on science, used one of Andrew Piper's pictures as the cover illustration for its new edition of Le Dilemme du Prisonnier (The Prisoner's Dilemma), William Poundstone's study of the seminal mathematician John von Neumann, his theories of "zero-sum games" and their role in nuclear policy during the Cold War.

The picture was made at Denver's own St. Patrick's Day parade.
