The Roman Dodecahedron - An ancient mystery solved?

Over 100 of these artefacts have been found across Northern Europe and, dating from around 200 AD, people must have been using them for something useful for there to have been so many made.
I wanted to see what they might have been used for so I got one made with a 3D printer and, well watch to see what they can do :)
