Been thinking off and on about "near future" space colony stuff -- Chesley Bonestell lunar colonies, 2001 space stations, even O'Neil habitats. Collected some pictures but that's a lot of planning and modeling. Biggest problem is the outsides are large but relatively boring (with little direct connection to the insides), but the insides are so cramped that without flyaway walls you can't set up any decent shots in them. So you'd have to plan out set pieces for maximum utility.
