I've seen this around quite alot actually... Its kinda like a map of Tolkien's Universe, with cards in it, and a ring, which you move around that board, a bit like Ouija, to get answers... I think there's more than just cards and a ring with it, but I'm not sure..
Anyway, it's pretty expensive, and I'm not a big enough fan of Tolkien to buy it...
Kiama
