When I as messing with this program around 1999/2000 I found the tarball was missing some of the example models shown on the website. I emailed asking about them and he wrote me back with the models attached. This must have been shortly before he died :(

ping got more attention because the original brl cad was only available from a .mil domain and you need to ask for a key to decrypt it. When it was finaly opened it was no more interesting .
