From the preamble:

A prealpha version of a port of musinum, a fractal music generator from 
Lars Kindermann.
See  (in any case...)

http://reglos.de/musinum/

Try MusinumPlayer base2
	or
MusinumPlayer base2base3
	or
MusinumPlayer random3to7
	or
MusinumPlayer randomPercussion

Right now you have to manually interrupt with Apple/. or Alt/.
and then say

MusinumPlayer reset

So it is an euphemism to say that there is no user interface,
but I still found it interesting enough to dare a first release.
You have been warned...
