When you open Tone Matrix, it looks similar to the beginning of a game of Minesweeper, a field of shaded boxes. However, as you click or drag across the squares, they light up and create different synthesizer tones. You end up with your own light, random (or carefully calculated, depending on your approach) music. Don't underestimate this game's addictiveness. This is great for music lessons, but also for looking at mathematical patterns. Watch it in action below.
