That is very cool. A little net.homework tells me there was also a
digi-comp 2, which sounds even cooler:

<< I actually owned such a monstrosity, although it was a kit rather than
a DIY project. I've forgotten the manufacturer, but the product was
called the DigiComp II. It involved marbles rolling down an inclined
board, wherein were mounted plastic flipflops that actually flipped (or
flopped) as a marble passed them. If I remember correctly, the word size
was 12 bits. I definitely remember an accumulator and an MQ register (set
with non-flipping switches), so the thing could at least add and multiply.
It was not, of course, stored-program, but it was a true digital computer,
and binary to boot.

Who has one?!
