Swedish artist uses ARKit face-tracking to create fun optical illusion on iPhone X

A Swedish artist has created a fun app which uses ARKit’s face-tracking and the 3D camera of the iPhone X to create a somewhat spooky-looking optical illusion...

By tracking your eye position, and adjusting the image displayed on the iPhone X screen, Peder Norrby is able to create the illusion that you’re looking down into a three-dimensional hole.He explained in his original tweet that there are no video effects in use, it’s all done in the app.
