One of my friends back in Winston-Salem, Kent, works with stained glass for a living. He's had many cool creations. The latest he had to show us was this box. When closed it can be turned every which way and the lid stays tight. In order to open it you twist the knob one way, lift up, twist the other way, and lift the lid off. I want one! He says he's also working on some more boxes, influenced by the Hellraiser puzzle box.
