The section "The drawings and the game" is amazing.
When I was about 5, I saw this machine where art would go in, and much more detailed art would come out.
I must have been confused about how it worked (I think it was just a badge laminator and I had been confused about the inputs and outputs)... but it occurs to me that we actually have that now.
The magical machine my mistaken mind dreamed up as a kid is actually real now, and that's nuts.
