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.

"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.
