I have been writing software to explore geometric transformations and create Escher-like tessellations for twenty years. My programs include The Geometric Golfer, TesselMania, Kaleidomania, and Tessellation Exploration. My newest program for designing tessellations is TesselManiac. In TesselManiac I have added code to control a laser cutter. This allows me to create the tiles out of real material like acrylic or wood. In this video I demonstrate how all of this comes together to create a tessellated chessboard.
