QuickTime Virtual Reality

If this doesn't show you how much better QuickTime is than Windows Media Player or RealPlayer, I don't know what will.

Here are two links to some amazing QuickTime VR sites that have a lot of fullscreen panorama VR from all over the world. Of note, this page has underwater VR, and one from the top of Mount Everest. On FullScreenQTVR, there are 360 panorama shots of the Colorado River, the Grand Canyon, and Mars. There are many more high-quality ones on there, as well.

Definitely worth a look. Dial up users, it might take a while to load.
