These are fun projects. Even in the simple case it's somehow kind of magical and the effect can be remarkably compelling. I made a simpler desktop version as a game years ago, with a small team at RHIT's "Catapult" summer camp. Not sure I still have the code for it sadly. We had a custom software 3D renderer with OpenCV face-tracking for both the parallax effect and steering the player character around obstacles.
