I had modified Charles Forsyth's 2e MineSweeper for 3e to use the
control(2) library heavily -- each square on the grid was a control
widget, all sharing the same channel on which the main chunk of the
code sent messages around.  the control library also took care of
displaying the bitmapped images.

I found libcontrol perfectly capable of standing on its own.  At the
time I was unhappy how some of the components behaved, but changing
them also proved painless.

It broke when 4e came out (I just found out recently) due to a change
in the control message convention.  I haven't bothered to rewrite it
(it was just an exercise in using libcontrol) because it was
superseded by a more colourful and correct interpretation of windows'
