I went again about three years ago, on a visit to Seattle, and the entire time I kept thinking, 'this is just a Windows Media Player visualization. My iPod can do this'. It wasn't unpleasant, really, it was just a recreation-asaurus. I can't imagine they're still around.
Another thing that struck me as I was watching this is that you rarely hear the 90's catchphrase 'someone has too much time on their hands' anymore. There are still a shitload of people who objectively do have too much time on their hands, but it's no longer populist-cool to derisively mention this when viewing other people's creativity. Whoever made this video clearly spent a fucking epoch making it, but what else was he supposed to do with his time? I think it's great that people have so many opportunities to 'waste' their time putting something new into the world.
Come to think of it, you never hear 'talk to the hand' anymore, either. But that's because the UN recognized that phrase as a human rights violation, and banned it within the OECD.
