This is Mortal Coil, a 3-D printed skull slinky designed by Ryan Kittleson. You can buy one on Shapeways for $50. Skulls are cool. We all have one. Some people just have less going on inside theirs. You know who I'm talking about. I'm talking about that really stupid person we all know. I'm talking about-- "Yourself." SURE AM. If my brain were a motel it would be all vacancies, all the time. I'm kidding, if my brain were a motel it would be the Bates Motel. Only really twisted shit goes on inside there.
Keep going for a video of the skull in action.
Thanks to TBTMH, who agrees the sweetest skulls are the two from that couple in the eternal embrace.
