I might take a stab at building one of these games:
I fondly remember playing Nim in a discrete math class in college.
I could have sworn this came up a few months ago, but not finding it via search… Anyhoo, have you seen this:

There’s a video (sadly non-linkable) on the page…
I’ve wanted to build one of these since I first saw it a few years ago.

That’s the same outfit that does the Egg-bot.

Yep… They also sell Solarbotics marble machines, which look
like fun:
The laser cut spiral is intriguing…

I definitely want to build one of those as well. Great for teaching kids about binary and logic.

I think they also carried this LED project kit (but can’t find it now)
My lab manager was not amused, btw…

Ooh. We had a digicomp 1 when I was a kid. Also, assembled that solarbotics kit. The spiral works pretty well, but over the long term the kit is a lesson in the non-rigidity of thin amorphous wood products.

I put the files to my marble machine online, it’s a slightly older version to the one I sell through solarbotics but it’s still perfectly functional

I had a Digi-Comp I, back in the 60s. The Digi-Comp II was from later in the 60s. It’s super-cool that Evil Mad Scientist put it back into production. I’m not sure why they call it “First Edition” though. More details at http://digi-compii.com .
