@tinfoiling thank you! Working on this book became a side hobby. After year 3, it gave me and my friends who worked on it a reason to meet regularly and chat about our progress and other cool math and art stuff. Unless we sell 100,000 copies, it’s never going to pay for all the time we put in it, and that’s okay. It was fun, beautiful, and content worth sharing with the world. But maybe, just maybe, we’ll sell 100,000 copies. That’s only 1 in every 83,000 people.
