Three-channel video installation and sound

I am showing a video that I filmed with my mobile phone in my everyday life and two fake 3D nature videos. I created a natural soundscape from artificial noises. This video changes to a blue and green screen when a person is walking on a treadmill.

Every visitor can run a fake run in front of a fake background. But when one stops running, the fake nature and sound go away. Only the real documentation video remains visible on the floor.
