Obviously, cool things built of out LEGO's are keen candidates for a WiX Working Group video. The Rubik's Cube solver was pretty sweet. I'm not sure tonight's LEGO creation is quite as impressive but watching the gears all work is cool. On top of that the video editing and totally appropriate soundtrack pushed this one onto the must watch list. Check it out.
Oh, and stay for the blooper reel to see just how real it really is.
