Have been working on this spaceship, see, that might, or might not, be in a webcomic. This is a bit of a redesign based on a great website called ATOMIC ROCKETS. The cone sections in this image show zones where you don't get killed due to radiation from the reactor/nuclear engine when they're on full (though you need a radiation suit in zone 1)! The whole things about 200m long now, and half the superstructure’s still missing.
I'm having great fun working on this in OpenSim, even if there's never a webcomic from it .
