@ninawillburger They are time artefacts of #DrWho. Look at these remaining balls! It was a horrible time when the Celts invented their #dodecahedron time changer games, and a Roman soldier forgot to close the teleportation gate. The #Daleks materialised and stole the inner material to build their sense globes: https://www.youtube.com/watch?v=YSLQH1gKocs
Since then, a certain Gallic village (the game inventor lived there) was angry at all Romans until Dr Who will return and bring back the sense globes!
