is this bloopsophone code?

It's actually a hacketyhack program, but hacketyhack thinly wraps bloopsaphone with some builders so that you don't have to manage any object state directly. This is not a very good song, something I played with at why's art&&code lesson, but I was using it to show how all these undocumented methods work: http://github.com/hacketyhack/hacketyhack/issues#issue/31
