VR  and Kinect experience but focused on lack of motion — a form of meditation, but as you are able to stay still, the scene around you changes, exposing tranquility to you?

Deer could come out, birds make noise, flora and fauna, etc. And sunlight shifting through trees, colors.

 

If motion is detected, it slows/fades your experience a bit until it is entirely missing again and you have to start over.
