To make this even easier and not worry about label alignment, print onto
printable CDs with a printer such as the Epson 300G.

A couple bearing, a plastic rod that just fits the CD hole, some spacers,
stack the whole assembly onto the rod to make a giant pasta cutter and then
use an LED/Photocell on a stick to reach each disc.  Could even print
multiple patterns per disk selected by moving the head assembly in or out.

It'd be like an optigan with a kill radius.
