How to Cast Shadows on the Moon

The moon is roughly a hundred times further away than it is big. If you want to cast shadows that fit on the moon, how big would the setup have to be? So if you made tiny, tiny puppets, you could hold them like a meter away from a torch and they would cast the right size shadow. That's quite a lot. What a normal size torch. I'm not, because they're not asked here how bright the torch would have to be. We'll get to brightness later - there are other problems with this.
