Secondary Supply

This is a control panel on the elevator at my university. I really like the buttons.. "Primary Supply", "Secondary Supply", it sounds so manly.

Then there's the 'Press to Speak", which is just genius, though I usually speak without pressing a button. I also like the 0/1 switch which doesn't indicate in which mode it is.

And of course the nice graphic of what's going on. See that man's chest? He's huge, but still he's trapped in the glass cage. Unfortunately for him, the fireman has been replaced by hot flames / tentacles, so he shouldn't expect any help soon.
