Chad’s been playing this one ever since he got the link from his brother (the brother-who-may-not-be-named-on-the-web). It’s an interesting concept: some 100 odd squares inside a large square. When you click on a square it gets played; or rather, there’s a playing “pulse” running through the square from left to right, and any note you have highlighted, gets played over and over again.

What happens is that you can make visual musical gestures. Chad’s been playing his initials, my initials, and other random patterns.

Play with it here. It’s called the Tone Matrix.
