Somewhat OT but somewhat relevant too.
We just opened 2 new Fire Stations, our department maintains municple facilties and I am the lead for our department, so I am there during the training for the Fire Captains and our department.
Here is where it gets funny.

The new station is controlled through a virtual screen on the wall, really pretty cool. Everything is controlled through this screen, lights, bells, this part lights up, this part doesn't, etc. Just basic stuff, nothing that controls emergencies.
I ask the inane question of, "So when this screen/device goes belly up, how do we circumvent it?"
"You can't. It won't go bad."
"Excuse me, we can't go direct with a laptop or through a computer program interface, anything?"
"Nope, no way to control these parts other than through the screen interface. It won't go bad."
"Ahhh, I see."

Comitted to excellence through art.
