3D Dewey Data Visualization is a project by Syed Reza Ali built in Processing that explores the topics of 3D Space, particle systems, OpenGL and java, alpha blending, bill boarding, user interactivity, self-organizing algorithms (Kohonen), and electromagnetic attractions & repulsion.
The project uses one year of transaction data (books, DVDs, etc) from the Seattle Public Library to drive the visualization. Each particle/sphere is given properties, such as what category/subcategory it represents and how many items where checked out in that category. This is used to drive the physics system that is used to separate the nodes evenly on the surface of the sphere.
You can read more about the project and interact with the Processing java applet on the website
