The short and the tall of it...

A characteristic feature of the Rings trilogy is the appearance of people who are very short (hobbits) alongside people who are very large (Gandalf), or at least of average size (elves).

Ignore the bellowing voice which periodically announces "You shall not pass!", and make your way to The Scaling Interactive to find out how they make such a snug fit together on screen.

The trick here is to saw the bench from Gandalf's cart in two and use two cameras and all sorts of other perspective-bending trickery. Take a chum, say cheese and get some different-sized friends.

For more interactive adventure, I direct you to the Ring Experience, right in the middle of the exhibition. Enter one of the Cracks of Doom, cross the lake of lava, and listen to the voices that echo around.

Sooner or later, one of them might spill the beans about how the third instalment of the trilogy, due at the end of the year, turns out.
