Although I'm not completely satisfied with this (the stone walls are awful), it's not terrible for a neophyte! When I started this, Hexagon 2 had just come out, so thus was created the geometric chess set. The Bishops are strange, but otherwise they work.

The wallpaper name is the opening of the game in progress (aka the Spanish Game). It was named after some 16th century Spanish monk who analyzed this opening in his Libro del Ajedrez. (He also included "strategies" like setting up the board so the sun shines in the opponent's eyes)
