So I’m quite a fan of scifi, especially the classics so this was always going to be a model I would try doing…. it’s more of a proof of concept at this stage, but I definitely want to work on this some more.   Perhaps with some landscaping (hills and water features?).

Ringworld is scifi novel by Larry Niven and you can read more about it on the wikipage…
