I have been using that as a screensaver for awhile now and, I must say, it is pretty good.
Even better is when you are listening to reall good music when hooked up to a large display with the lights off except for the CCFLs in certain foot/ceiling spotlights to project shadows on the walls; and, NO, in case you are wondering, this has nothing to do nor indicates I spent my time throwing a party or some such when I wasn't here.
