"Fidg’t is a desktop application that aims to let you visualize your network and its predisposition for different types of things like music and photos. Currently, the service has integrated with Flickr and last.fm, so for example, Fidg’t might show you if your network is attracted or repelled by Coldplay, or if it has a predisposition to taking photos of their weekend partying. As the service expands to support other networks (they suggest integrations with Facebook, digg, del.icio.us, and several others are in the works), this one could become very interesting."
This is a data visualization of diggs on digg.com. It works so that the more people that diggs something on the web, the higher the stacks get. This is a real-time visualization and it is more then easy to spend a few hours here.
"Taglines from Yahoo! Research allows you to visualize Flickr tags over time. For each day, dating back to June 4, 2004, the eight most popular tags are shown with a photo selected for each. You can view Taglines in waterfall mode, which displays eight tags and respective photos in eight rows, or in river mode, where tags and their photos “flow” from right to left."
