Just look at Frankie Lymon's head. Just his head, don't take your eye(s) off his head, specifically the upper head, from the eyes all on up the forehead. Pretty soon it (his head) becomes detached from his body, like it's just hover-flaoting above it.
And then, it gets WEIRD.
It's like one of those Magic Eye cartoons, only this eye gets evil. FLOATING BIG HEAD EVIL.
