I posted earlier about interesting things that might happen if more people blogdumped as Tom Coates did, and some nice visual examples of blogging behavior are coming out. After my post, Coates subsequently lamented that there wasn' t a deluge of interesting vizes, but these things are hard work! Heck, it probably takes a little bit of time to figure out his data format and then a good way to interanlize.
In any event, through the follow up work I ran across Tom Carden's processing sketchbook, a collection of interactive applets generated using processing.
