Agreed... but apparently cal /does/ want that. :-)

Related example:  THX's "Deep Note" was composed using a 
PRNG.  Every performance was different.  The "favorite" 
performance is the one you hear in theaters (with the 
descending overtones at the end).  At one point, the 
recording was lost -- and there was no way to recreate 
it.[1] If they had saved the seeds to the PRNG's, they could 
have recreated the performance (even with rand()).

     Sorry, can't find a reference ATM for the story about
     losing the master recording.
