Shades of Little Shop of Horrors' Audrey with this LED clock from Brit designers Jimmy Loizeau and James Auger. Part flycatcher, part timepiece, the gizmo harvests insects on a sticky roller covered in flypaper, before dropping the corpses into a microbial fuel cell.
The dead bug is then digested by the bacteria within, and the chemical changes are used by the cell to power the clock. Simple, huh? Well, simple if your mind moves in mysterious ways, I suppose. There's a close-up for fans of six-legged snuff porn below.
