On the way in to work today, I was listening to a Metaverse Session podcast (which is excellent, by the way), and they were talking about a screensaver called Twingly that shows a 3D globe and maps out in real time as blogs are posted from around the world. As soon as I got to work, I downloaded/installed it, and I must say it is pretty darn cool. (However, don’t look too close at the blog posting titles since — as expected — every once in a while, something NSFW will scroll by.)
You can click/drag the globe to see different areas. You can zoom in on different areas and see what blog posts are coming out of that location. You can click on a post title and get more information and a link directly to that blog.
