When I started to watch this video I thought I wasn't looking at a painting but a high definition flat display that tracked your eyes, modifying a 3D model to give you the illusion of real depth. And then the magics finally get revealed. It's so simple and so damn cool.
It reminds me of the T-Rex illusion that follows you anywhere you go.

Holy shhhhh! Is this how they do the faces that follow you on the Haunted Mansion ride at Disneyland?
