The video is bad quality and the screenshots were taken with a digital camera. Just some interesting tidbits on the next generation windows operating system codenamed "Longhorn". These show the new effects being added to Longhorn to step it up a notch in the operating system realm.
While the images and video are low quality they do show that Longhorn is coming along rather well.
