The Warped Chessboard
This chessboard is seen to curve or warp in the middle, since on one side, the pieces are placed under the board, while on the other, they are placed on the board. However, all of the lines are perfectly straight and parallel. This illustration incorporates the same double-perspective in the chessboard and the ladders that was used in one of my first works, The Window Gazers.
