I don’t know if using a single logic gate really helps in getting across the logic behind computer circuits
That's entirely the point. A NOR gate is functionally complete: you can build any logic gate out of just NOR gates.

#22The Dutch childrens magazine Donald Duck included a DIY cardboard 3 bit computer in four editions in 1980. It was powered by a marble and gravity and it included QA cards, like “What shall we eat? followed by three questions (hungry? Want sweet? etc) and then on the back of the cards there were eight answers. You set the switches to left or right, put in the marble at the top and looked up the answer corresponding to…

#23This made me imagine an educational toy that allows you to make working simple circuits by drawing: You draw with markers that have electrically conductive ink, then touch the contacts of a 9-volt battery to your drawing at a certain point and a bulb or LED that you've taped to your drawing lights up. Maybe you'd supply prefabricated stickers that contain logic gates that you stick to the paper where you need a gate.
I used to do this with a graphite pencil, battery, simple 1 transistor amplifier, and a piezo buzzer.
Lots of fun. Makes me yearn for the days of radio shack.

You can, but then I don’t see the point of making it a colouring book.

Probably because it's easier to have to know only one rule.
But... they got a character named "nory", having another character named "andy" could be fitting!

#26Ah, the title is truncated non-electronic computers that work when you color them according to a simple set of rules.
Submitted title was "Coloring computers: non-electronic computers that work when you color them acco". We've lopped off the end bit above.

#27It’s cute but it just makes me miss the days where kids could go to the library and load up Rocky’s Boots on an Apple ][. That’s how I learned logic gates and it stuck. https://en.m.wikipedia.org/wiki/Rocky%27s_Boots
And even better in my opinion is the sequel Robot Odyssey

There's a disk image at the Internet Archive https://archive.org/details/msdos_Robot_Odyssey_1985
And even a re-implementation for browsers https://robotodyssey.online/

#28Earlier quoted context omitted.
It's too general/abstract. Instead of a square color and circle color, just pick two colors and go with it.
I guess the reason for that is making the instructions understandable even if printing in b/w.
I think it's just so you can choose two colors that you have and fill in the instructions.

That is very cool, a bit of Google Foo then gave me this:

That and Google Translate will allow you to build your own.

I picked up exactly that at a maker-faire type event a few years back. Might have been this product [1] or something similar.
