Hard Drive Speakers

So yesterday at work John and I put forth effort to create speakers out of old hard drives. We have a lot of hard drives and free time. Sounds simple enough, all a speaker really consist of is a coiled wire and a magnet, but we had little luck with the whole thing. We got some streaming techno over our hard drive speaker for a short time and very quietly. None-the-less, it was a good waste of time and we made a mess while doing it.
