Penrose Empires swMATH ID: 5381 Software Authors: Jason B Healy Description: The Java Penrose Empires Package allows you to compute the empires (forced tiles) for an arbitrary initial patch of tiles. Tilings may be saved for later, and may be exported to PDF, EPS, or PNG. This software represents a new method of computing forced tiles. Rather than using a ”growth” approach (where some tiles are randomly forced), this system only shows the forced tiles in the system, leaving all unforced areas blank.
