re: Tell you what I want, what I really really want
Hey E.P., if only had the time to do what I really really want I'd be generating videos from all the animated gifs NASA has ever put out :) I remember seeing an animation of either Neptune or Uranus from Voyager images, but I've got no idea where they are on the web. But here's a link to some Jupiter animations.

As for the MPEG files, they're just to big. I plan to have a lot of videos on my site over the next year or two and I have to balance file size, quality and users' dial up speeds.
