Side story — It was an emergency art. I’m a really lazy designer. Drawing something just for a blog post is not lazy person’s favourite thing. So I skipped at the first time.
However, I didn’t know the link from Medium automatically picks up the first image from the post. Which was Marius Watz’s artwork! How dare I present my “Conquering mathematics” experience with my idol’s artwork!
I was urgently working on the cover art, and that’s how it came out. haha!
