I've heard people joke about using hamster wheels to harness small amounts of energy, but this is the first time I've seen someone enlist the pets to help in their Ollie-North-by-Northwest schemes. That's right it's the very first Hamster Powered Paper Shredder, for all your secrecy needs! (Note: it's only a prototype as of now). Still, the idea just feels right. Not only does the hamster help line his own cage every time he runs on his wheel, but every bit of exercise gets rewarded with a giant ticker tape parade. Of course, the only drawback seems to be if you've got a lazy hamster. Mine were always of the procrastinating sort, and I'm not sure paperwork agreed with them. Link via OhGizmo.
