So Heather asked:
I still can’t get past how neat this image is. It’s one of those things I would have love to have seen illustrated, complete with fading zeros, in a book when I was a kid. And now. Thank you.
What’s the predominating color theme?
So now you done it. I’m not sure there’s any colour theme per se. But I once tried to represent them in space, and have approximated that here. It’s really rough, because most of the colours are off, I’m using a grey background to show up most of the letters, and because I can’t do the light and shade part where they go through the rabbit hole.
