Wow, check out the video tour of Evil Mad Scientist Laboratories’ functional recreation of the classic educational binary computer Digi-Comp II.
Several weeks ago, we talked about bringing our giant Digi-Comp II to Maker Faire. But now we’re back, and we wanted to show everyone how it works– not just the many folks who came by to see it at Maker Faire. For those of you just joining us: The Digi-Comp II is a classic 1960’s educational computer kit– an automatic binary digital mechanical computer, capable of conducting basic operations like adding, multiplying, subtracting, dividing, counting, and so forth. These operations are all conducted by the action of marbles rolling down a slope, directed by mechanical switches and flip flops that act as logic gates. Our version is a modern, larger-than life remake. A functional clone, but sized up to use billiard balls instead of small marbles.

That was delightful ..(nostalgic as well) thank you!
So the “halting problem” (http://en.wikipedia.org/wiki/Halting_problem) has been solved! it’s when the balls stop dropping ;)
I had a Digi-Comp II in the 1960s. Watching this video felt so familiar.
This way of visualizing computation is COOL~~~~~~~
