Is Chem-Mod still around?

At one point there was this SVN for a thing called Chem-Mod, and it looked really fun, but now I can’t find it anywhere on the web, so I came here (which I might later find out to be a mistake). Does anybody know what happened to it, and possibly still have the SVN for it?

Be more specific of what you are looking for, someone might know it, but not by name. I have never heard of it, though.
