I'm adding some gratuitous eye candy to vulcan. This makes things even more confusing than they already are, but I've been meaning to experiment with that stuff for a while. It will make screenshots for sites such as freshmeat look a bit nicer, but I'll probably make it an option that will be turned off by default.
More importantly, I replaced the 3d models with free ones, taken from the xscreensaver mode "endgame" (which, in turn, took the 3d models from glChess). Not only are these models free, but they also look much nicer than the ones I was using.
New version to be released Real Soon Now.
