Has anyone come across, made or be willing to create any models for Niven's Ringworld?
I have the inclination to recreate something called "The Fringe War"

Ideally a space mod of the ringworld, a planet model of the ringworld, and a set of "General Products" hull models for Kzinti, ARM, Pierson's Pupeteers, Trinoc, Outsiders...
Note these models should be pretty simple to create, very straightforward geometries... Only the ringworld itself as a space mod or planet will be tricky. Hmm if I find the time I may do so myself... what's that new free setup for SFC modeling again? (Though I'm sure others would do better than I...)
