In this case, what you see is what there is. And I can say that with some
certanty since the object in question resides about three feet away from my
current position.
There are no hidden springs or rubber bands used on Dr. Nim. Like the
Think-A-Dot and DigiComp-2, it is cycled totally by gravity and the weight
of the marbles.
The mechanisms in all three show some commonalities in their designs.
Along that line, I've been tinkering with an 8 foot tall (!) version of the
DigiComp-2 using billiard balls to display at VCF IV. B^}
