Test map for a 7-segment display controller. (http://en.wikipedia.org/wiki/Seven-segment_display)
It turns four bits of input into the hexadecimal digits 0-F, displayed by retracting bridges.
Demonstration: http://mkv25.net/dfma/movie-1092-7-segmentdisplaydemonstration
Each gear is controlled by the lever of the same color in the control room, and each pump puts water onto a plate that triggers the controller components of its own color.
I could have linked the inputs levers directly to the controller logic, but I wanted to test this pump-and-plate setup too, which will allow me to make the controller display a number fed in from somewhere else; I'm thinking of making a four-bit counter. - Kanddak

"7 segment display controller"? what are you trying to build? sounds interseting.

Take a gander at your clock... (pref the digital one, analog is rather pointless for this exercise)
Now, you might notice that each individual number being displayed is made up of... smaller parts. You might call one of these parts a ... segment? sounds good. Each number on your clock is made up using seven on these.
So with a 7 segment display controller, he can easily represent the numbers 0-9, and probably do a good job depicting some letters as well, though things like R and Q are a little complicated.

Ah, I've never heard the term before.
