Just beautiful

This is actually just an interesting optical illusion like Crow T. Robot in Mystery Science Theater 3000. You can't tell from his silhouette if he's facing the screen or the camera.

Same principle here; the head is being rendered in wireframe and you're seeing the ordinarily invisible reverse side of every polygon at a high enough densiy that it looks solid. Of course it's much more enjoyable if you don't know any of this :)

That brings "having eyes in the back of your head" to a new level.
