Graphics help requested: making a progress bar for the theory club

I am working hard on a book club over on /c/theory trying to help comrades read through Das Kapital volumes 1-3

It seems daunting, but is actually a finite slog that will definitely be accomplished provided you keep putting on foot in front of another.

So I'm trying to keep comrades motivated in any way possible. I was thinking some visual progress indicator like the mock-up attached would help motivate and stimulate comrades. Can anyone make such a thing for me?
