That one website that lets you make a pretty tune by clicking squares on a grid

Why it's the pick

ToneMatrix is a 16-by-16 grid where every square you light becomes a note in a scale that always sounds nice, so anyone can make a looping melody in seconds and share it. It is free from the Audiotool team.
