Andy Woodfin created a utility to take a TGA image and convert it to a set of 3D objects for rendering in POV-Ray. He called it TGAMosaic.
After receiving various requests for the source, he decided to release it under the GNU GPL. Since he's working towards his PhD, and I went and opened my big mouth, I ended up taking on the job of maintaining it.
There are various things that have been talked about for doing with it, but for the first step I took the original sources and cleaned them up enough to compile and run under RedHat Linux 6.0 on Intel.
