I had forgot about the Sum Some Sines .... that will come out ... it is a program on the processing language that lets you play with adding sines. It isn't a simulation of the machine, but it is fascinating and instructive. We choose not to release it with the machine vids.

A note if you're not aware of it (though you probably are): processing has an offshoot called processing.js [1].

That version can run most processing apps within the browser with no plugins or setup, thus letting interested users just visit a link to use the app.
