Interesting 3D print here I found on Shapeways with the help of 3Ders. It's a 3d printer skull which stretches like a slinky does, called the Mortal Coil. As you can see in the video below the image, it will always go back to it's original skull form once stretched. Ryan Kittleson is the designer of this thing, and you can buy the White one for $49.99 or the black one for $59.99, made out of black flexible plastic on Shapeways here: http://www.shapeways.com/model/1681652/mortal-coil.html
