Blog data is collected from all over the world and streamed in realtime via Amazon S3 to all instances. Data is visualised with OpenGL, and the location of each blog post indicated on the earth using the lat/long of the server. Not very representative, since most large blog tools are hosted in the US. Language detection would have been more appropriate.
See YouTube video of the visualization and it's possible to download the screensaver on www.twingly.se."
