I have forked the joons library (from googlecode) to github  joons-fork.  I did this because I wanted to learn how Joon Hyub Lee had managed to implement sphere primitives (something I would like to do with my povwriter library). Anyway I could not resist hacking the library, so I've updated it to work with processing-2.0, and re-based it to use sunflow-0.73 (cf sunflow-0.72). But I didn't stop there so I have also changed quite a bit of code (so if I've introduced errors blame me). You should know that not all PGraphics has been implemented in the joons library and shape(PShape) in particular has not been implemented. Read about the original library here, see my experiments with new library  here and here.
