The Space-O-Rama is impossible to describe coherently - it's beautiful, complex, entertaining and really really cool.
The build includes some commercial space which is all in keeping with the theme - I saw no naked/bondage/skanky/tacky/ stuff you can find almost everywhere. Very nicely done!
The highlight for me is the SteamPunk Air Museum. It includes the most amazing and amazingly detailed machines that would make Jules Verne moan in envy.
You can sit on the flying machines to see them operate (you're inside the museum so they don't actually take you into the sky - you really wish they would though).
I'm so glad there are people like Sextan inworld sharing their talents with us.
