Gbloink! is a "sound toy" : a program that lets you produce music from any
Windows PC with a Midi soundcard or external Midi synthesizer. I'm
interested in both music and user interfaces, and Gbloink! was written as an experiment in both of these areas.

Most researchers in computer
composition use some grammatical or statistical model of the structure of a genre of music, and then ring the changes on this structure; or use it to filter a stream of random notes.

Gbloink! isn't a mathematical model, it's something you just play with : three balls bounce around a play area. When one collides with an object, it triggers a Midi note whose pitch depends on the vertical position of the ball.
