Usability 
PAW = PDA Animated Weather. An amazing site from the University of Wisconsin. Over 100 different animated satellite and radar weather maps. The maps are 300 px wide animated gifs and are zoomable and scrollable on devices that support html image maps. Not the most mobile friendly site - you select a map from a huge scrolling list but the maps are gorgeous. How well this site works, if it works at all is highly dependent on your browser. Opera Mini makes a complete mess of this site but my phones built-in Openwave V7 browser does a pretty good job with working animation and scrolling, etc. via a set of links below the maps.
