I saw a really cheap and dirty do it your self version in Popular Mechanics
ages ago.  Go out to the hardware store and buy two push buttons and two
light dimmers.  Glue the knobs on the two dimmers together and hook them
up to the lamp terminals on the carousel.  Glue a tinkertoy to the knobs
and mount the pushbuttons so that they get hit by the tinkertoy when at
the end of the travel (one on each end).  Hook the buttons to the slide
advance.  Then just keep swinging the tinkertoy from one stop to the other
to advance the picture, disgusting right?
