I've always said that since disposing of the "beige box", Apple has always led in the industrial design area. The integration of form and function can't be touched by any other manufacturer in any industry (Porsche comes close). It's a shame to clog up landfills with something attractive and durable just because it's original use is moot.
For this instructable you will need (ideally):
Apple Pro Speakers
a 12v motor with a shaft diameter not bigger than 1/8" and a housing no deeper than 2" (The ideal motor should have 3 or 6 threaded holes on the output side. The one I used was a samsung capstan motor from a trashed video deck. The most important things are the threaded holes)
a rubber band
a big nail
super glue, or really, really good glue, let's not get too high on ourselves now
a reamer-like file (I used an old phillips screwdriver, I had time to kill)
bolts that fit the threaded holes on your motor
a 9-volt battery
a 9-volt battery connector with useable leads (see parts source in the next item)
on-off switch (destroy one of your, or your friends' children's battery-powered toys - they need to use their imagination more anyway!)
soldering iron (or you could forgo the switch and soldering iron and just twist everything together)
a wheel from the toy you busted up - minimum diameter 1 3/4"
1 bottlecap leftover from your Laptop stand from 4 bottlecaps
3 nails or other hard, metal, pointy things
