Oh, this is really cool! :) I recently made something similar (also uses TFjs for the head tracking): https://compassionate-murdock-82fdbb.netlify.app/ (source here: https://github.com/ath92/blazeface-css-parallax)

Yours seems a little faster/smoother/nicer though, so props for that. I used CSS to place the 3d objects though, so that might have something to do with it.

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.
