I worked on an interactive screensaver and multiple web pages that delivered personalized news, weather, and sports.
The screensaver was built in flash and had the ability to pull stories from news feeds, update stocks, update live sports scores, and deliver alerts. When idle, the stories would cycle and animate across the screen. Moving your mouse let you interact with the screensaver and go directly to any story you wanted to see.
It used Push technology from PointCast, but with richer graphics, video, flash animation, and no strain on your bandwidth.
