inb4 it was an actually an elaborate prank to the media by Elon.
This is cool, i have these two humanoids in Blender, and both react the same to light: depending where the light is, one side gets iluminated and the other gets dark
The cool thing is, that one is a proper model, and the other is a mere image in a plane.
Why is this cool? With this technique you can have things in the background reacting in detail with the ambient light with just a fraction of the geometry needed.
