I am halfway done with the C deck, as we are switching to C soon, and I will setup a kickstarter after, should be done around December.

I want her to know why x[3] and 3[x] are the same thing.

    int x[3];
    2[x] = 5;

    printf("%d %d\n", 2[x], x[2])

A lot of people struggle with

    x = 5
    y = 6

    y = x

    x = 7
    print(y)

and

    x = [1,2]
    y = [3,4]

    y = x

    x.append(5)
    print(y)

There is something magical in understanding how the computer uses its memory, its almost as if you walk out of a mist.

I think it will be very valuable to have a set of 4 decks: python, machine code, unix pipes and C, so that the decks compliment each other. In the machine code deck there are few cards that have pointers (e.g. https://punkx.org/4917/play.html#43), and they can be used to help with the C deck for example.

Then its LISP.
