Hallo!
Fastbreeder is essentially a 4 button synth. The idea is to grow code by
choosing from a range of automatically generated variations of functions,
you don't have to know how they work, but each function creates a sound
which can be selected by you. The following generation is then created
containing mutants of your chosen sound. You can refine and develop the
sound just by auditioning and choosing the best one each time.

(I once tried to make genetic programming in PD, but didn't finish it
... maybe I will try again now ;)
