As seen on Random Digital Garbage and Planetarium. Tools are a collection of data tools that provide advanced information based on the API. I have been a regular user of since December 2004, so I gave it a try. And here is my Artist Cloud based on my listening preferences. This is pretty neat indeed, I have four names lying in the middle.

Besides Artist Cloud, there are also Tag Cloud, Album Cloud, Friends Graph, Friend Soulmates, and Average Neighbor. If you are a user, you might want to give it a try.
