Log of the Astronef 3D illustrations. Mateen Greenaway's collection of 3D illustrations now includes a couple of images based on
Forgotten Futures II: The Log of the Astronef. As I understand it these are still work in progress, but already pretty good. Some of the other steampunk illustrations on the site are also well worth a look.
