Bored at your job, checking returned USB floppy drive? Make a Floppy Disk Drive RAID. This one really puts the 'I' in redundant array of inexpensive disks.

He made a 'stripe' array, which increases speed (but not too much, sunce he's still running it over USB. I'd like to see someone make a 'mirror' array, where you could, at any time, pop out one of the floppies and still have all the data intact, then pop a blank disk in, wait a few seconds, and pop another disk out at random, until all the original disks were gone. It'd make a great classroom demonstration.
