My son put me onto this corker video of Darth Vader busting some moves to Jackson's Beat It,
One of the coolest things I've seen for some time

It's from some Star Wars thing in the US, and there are other longer and more stable videos on the site, but this one is great to start with
Vader's complete with Michael Jackson's glove
