This is a three-dimensional representation of an organic molecule. It was rendered with PyMol from a PDB file downloaded from
The MathMol Library of 3-D Molecular Structures. Everything else was done wtih the GIMP. It looks good with Mosfet's Liquid theme.
This was really trivial to make. Just install PyMol, grab some PDB files from the web, and you're ready to go.
You should be warned that the molecule is THC. I chose it because it looked cool (not too simple, not too complicated), not to make some kind of statement. It shouldn't be obvious to anyone what it is, but if it offends you, don't DL it.
