Design student James Auger was inspired by carnivorous plants to make a clock that is powered by converting the bodies of dead insects into electricity. A roll of flypaper catches the flies, which are in turn scraped off and dumped into a fuel cell. It's an application of biomass energy conversion technology. You can watch videos about the clock at the link.
