There are plenty of attractive visualizations for Flickr images. But Tag Galaxy is certainly the spaciest. Enter a keyword and Tag Galaxy will search Flickr for related images. You can either click the big ball of gas at the center of your screen to see some of the images, or you can check out one of the little related-tag planets orbiting the center of your tag galaxy (or solar system, really).

The picture doesn't really do Tag Galaxy justice. Each planet is in motion, and you can navigate by dragging and dropping various parts of the screen. When you actually click on a tag to view the images, you can spin the ball around to find more images, and click an image to enlarge it.

Be forewarned, Tag Galaxy can make your web browser go Supernova if you're not careful. Firefox froze up on us a couple of times while we were playing with the web page. We also had a bunch of other tabs open, but Tag Galaxy certainly seemed to take a toll on our CPU and RAM usage.

thanks Sascha!
