just out of curiousity, how would one do this? with printers & overheads
its fairly easy to  print a semi transperant wheel, but how would one
convert the sound to something that you'd print?  Also, what sort of
diamater wheel would you need and what sort of RPM??  Im thinking a fairly
high RPM would be requiered to get the appropriate frequency bandwidth??

mmm, optical disk huh....  sounds like something else.....


Cheers,
