I was amazed by the Tiki Room as a child, and tried to build one in my
room, back in Minnesota.  Small world has great design (Mary Blair is
my favorite) though they recently redid the music.  It used to have
great arrangements, making the song seem less redundant.  One part I
particularily remember was a great screaming trumpet bit towards the
end.  Now it's all more homogenized.

It was the Pirates of the Caribean that they originally used rotating
discs to program.  Apparently the animators would carve notches in
cardboard discs, then later create wood or plastic discs from the
cardboard templates.  The discs would all rotate, stacked atop each
other, by a geared motor.  Naturally, these would actuate switches to
activate the various hydraulic cylinders
