Hamish Todd is fusing mathematics with video games in his new artistic puzzle shooter Music of the Spheres. The protagonist is an old man who has died and gone to heaven. He is now challenged to complete a series of puzzles. The game’s art features girih tiles, a mathematical based form of Islamic art dating back to the Medieval Ages. Players will need to shoot bouncing bullets that will play a note when impacting a solid surface like a wall and hit a a moving target. The result is a relaxing experienced heavily inspired by Portal.
