I can do the thing with lifting the ring fingers separately, and moving the pinky independant of the other fingers. My mom has a "hitchhiker's thumb" where her thumb bends back reaaaally far. I can also sit down and double my back over, so I can lay my head on the floor, and If I turn me head, I can lay the side of it on the floor. All that, and it's quite comfortable. My family thinks I'm weird because I've been known to sleep in such a position.
