An anonymous donor was kind, so kind, enough to send us a special sneak preview of how our RSS feed would look in the upcoming (when? oh when?) OS X 10.4 Tiger. We've got a couple of screenshots and a video encoded with Quicktime 7 using MPEG4. They depict a screensaver written in the new Quartz Extreme with a new developer application called Quartz Composer, that animates RSS feeds in, shall we say, a pretty jaw-droppingly slick way. Video link below, and peep another screenshot after the jump.
