[GZG] Bigger Than Worlds (was Ringworld)

Greetings:

Dig around for a Niven essay called "Bigger Than
Worlds". I think it is in a collection called "A Hole
in Space", probably others. He details various
artificial worlds, from asteroid to Dyson Sphere, etc.

One of the worlds is a ramjet ring. More like an
O'Neil colony diameter, not a solar-system-spanning
Ringworld diameter. So your RW model could double for
one of those ships, making it more in scale with your
FT minis!
