Very, very neat, yes. I hadn't noticed that Joss had linked to it, which gives it extra panache points.

(Although I'm still partial to the "I Need a Hero" video from the Babylon 5 blooper reel, which was a fine piece of editing. To my surprise, I can't seem to find a full copy on the Web, although one chunk of it is embedded in this remarkably silly montage of Babylon 5 music videos. I may need to upload my wretched copy of the full song -- IIRC, it gets better as it goes along...)
