TiddlyWiki, the personal Wiki where you store all your content in a single local Javascript-enabled webpage, now offers a new look: a desktop, complete with movable tiled windows. I’m not sure if this is a good idea or not (I can’t imagine using this look myself), but at the very least it’s an intriguing demonstration of what you can do with just Javascript and Cascading Style Sheets.
