Boston Dynamics Big Dog's big legs

Eerily 'life-like', especially when it slips on the ice:

BMW's shiny new fabric car

Well, it certainly looks like a BMW, upholding the visual style typically associated with a BMW car body, yet at the same time made out of a completely different material. The GINA concept car uses fabric stretched over a wire frame instead of pressed steel car body panels. Its light, its bendy and most importantly, it uses a fraction of the energy needed to make cumbersome metal panels.

Just don't leave it parked in a dark alley with knife-wielding vandals ;)
