At $40 a piece a 14 way Beowulf cluster is $560 using my spare 16 way Gigabit switch and an old network attached HDD, just need to get sufficient 5v for the 14 boards

Someone already has a WIP on clustering ARMs, but I was thinking Knoppix for the distro

Just need to convince my wife that it's a really useful thing to have about the house, any ideas on what I could possibly use a 14 CPU ARM cluster for? ("The hell of it" doesn't count with SWMBO)
