The blue is slush, I forgot the rocks, here is a new version of the sprites with all the basic buildings included.
Cool
@Matt the symbol being used for toxic is actually already in use (for hazardous material, irritants, don't breath this stuff in type of stuff. I see it all the time in the lab, see here for some symbols
http://en.wikipedia.org/wiki/Dangerous_goods)
Lets see those buildings: The resource buildings are easy enough
Factory, Industrial Park, [no automation?]
Heavy Fission, Fission (on actinium?), Fusion 1, Fusion 2 (neither of which we have seen before), Solar PP, Plasma tap, wind, geothermal, tidal, hydro.
Network, Media Centre, 5 levels of Data Centre
Next section is simple enough, not sure what the tourism centre represents, but I like the red light district. There is a blank space after the stock exchange then capitol, civic centre, provincial Admin and academy.
Next 5 symbols are new? Spaceport, Spacedock, Shipyard, Elevator, Fountain ???
4 Hab types, Spaceframe, Base, Dome, 2 levels of Cladding? I can sort of see the boxes being cladding material but whats that above them? Last 5 are Bunker levels
Only Automation missing. Only thing I don't like is the university, looks really bland (a couple of grey boxes)
