So many responses, I may be repeating stuff. From the main wallpaper (FIRST STEAMWORKS Scene 1 (High Res).jpg):

(1) The only human in the scene has a telescope/viewer. The line of site is just below the horizontal vent, and can be viewing the two towers beyond. Human player guides robot around an obstruction?
(2) There is the Escher-esque floating walkway with stairways leading nowhere.
(3) The four smokestacks at the top center remind me of the now demolished "seven sisters" smoke stacks at a Detroit Edison power plant. Although there are banks of anywhere from one to five smokestacks/steam vents.
(4) the pressure gauge is shown twice and each says "single arm". Need two robots, each with a single manipulator" to complete a task?
(5) Nestled below the blimp in the upper left is a citadel that appears incomplete. Some assembly to go with the arm requirement?
(6) There are several repeated images that appear in the main illustration as well as in the margins and below the main floor.
(7) Several images could be derived from scenes in museums such as the Henry Ford in Dearborn, Michigan and other locales.

And from the workshop scene. . . . . RAMPS !
