The upcoming PS4-exclusive "yoga-action-platformer" Commander Cherry's Puzzled Journey has one of the strangest uses of a camera I've seen.
On the surface Commander Cherry's is a typical 2D platformer, but it has one unique twist: you form the platforms by making shapes with your body.
That's right. Stretch your arms out for a bridge, kick off to the side to form a ramp, and crouch to form a box. Occasionally you'll be tasked with fitting your body into specific molds to trigger things in the environment.
