From the developer:
Weightless is a meditative virtual reality experience for the Leap Motion about inspecting space debris in a weightless environment. The exterior window shutters lurch into motion and mechanically shuffle open. Light reflecting off a nearby planet pours into the cabin revealing the space you call home. You put out your arms and push off gently towards the center console.
