The virtual cameras don't change (the games would have to be changed), so the parallax effect is not there. The only thing that changes is the grid of limes that obscures one image for each eye.

The only thing in common is that both have head tracking, that's all.

Yep, and that is exactly what I addressed in my first comment - that head tracking mechanism was already used in mainstream technology piece.

This reminds me of this demo from 2007 https://www.youtube.com/watch?v=Jd3-eiid-Uw

And also didn't the Amazon Fire Phone have head tracking?

Also found this, done on an iPhone in 2011: https://www.youtube.com/watch?v=7saRtCUgbNI

Or this table using a Kinect in 2012: https://www.youtube.com/watch?v=2CbiOikirrg

The "experiment" is _how_ head tracking is used, not head tracking itself. I agree it's not exactly new, but nobody bothered to make it for the iPhone X until now.
