Ah, thanks Felyne. Frankly, having once worked as a mechanic this 'mild profanity' doesn't trip my metre off.
OT RANT! DON'T READ! (you were warned)
As for 'upsetting the Christians here', the more that can be upset the better. As a Christian myself I feel a good number of 'us' need a good thrashing with a metre long cluestick. The 'conservative religious right' needs a good swift kick is the nether-regions. Sometimes I feel so very ashamed of my affiliation and what is said and done in it's name.
There's nothing 'photoshopped' about it! The 'floating' as you put it is because the wheels are well up inside those huge legs. Some traction beds will actually retract the wheels so that it sits firmly in the floor (this one the feet get cranked down). As for the lighting in the room, you're forgetting that this isn't direct light! Photoshopped indeed! Hey, you know they faked the moon landing right, you can tell by the light and shadows ;)
Keeping power on keeps people out, reduces street mining and keeps the ventilation system working. It's cheaper in the long run then letting it deteriorate and having to fix it up later.
Power is often kept on to discourage street miners from stripping out the copper. Places like this get power at a bulk rate, what it costs is less than the labour of watching for looters.
You sure the ghosts just aren't people in glowing masks?
Sorry folks, I've been in many places where there are supposed to be tortured spirits, whether infants, children, ordinary schmucks or solders. Only thing I heard was wind, creaking timbers, furry animals or even machinery (in active buildings). But I've never seen anything to make me believe that there's ghostly bodies haunting the dark corners of the room.
Looks like some stripping has occurred here, the radiators seem to have vanished. If you look under some of the windows you can see the unpainted wall where a 'roller' wouldn't fully reach.
It'd was the fashion of the time (60's-70's) to modernize rooms in this way. It may seem stupid by today's standards but it wasn't that way then. Odds are it's still under there though in poor shape no doubt.
Mind you, one wonders just where the ones that are for internal use are. I expect that this has adhesive letters which have come off. I'd love to see a high rez version of the image.
