Here is a vision of the The Known Universe using Partiview.
Partiview (Particle View) is an OpenGL-based program available for Windows, Linux and Mac OS X.
It visualizes and animates three dimensional particle data. With Partiview, you have the ability to navigate through 3-D data as if you’re “flying.” Partiview is not limited to particle data; it can display 2-D images as well as multiple 2-D polygons that can be built into 3-D surfaces.
