While they do use box and pointer diagrams in lecture 2a, I was not
referring to them

I was rather referring to the capital A drawn in a rectangle. And then they
introduce some functions that act on such drawings, for example one
function flipped them

Some other functions stretched them or repeated them several times to
create fancy patterns.

I have taken 3 screenshots from the lecture footage for your reference


Thanks again
