A shirt design I just finished, you can vote on it here. It's what I call a "cheat shirt" for all the warp zones in the three Mario games for the NES. It's a little different, but I've been surprised by what has taken off before. Plus I just really like diagrams, which makes me a special kind of nerd. I also like the strategy guides for video games where they actually draw out the levels by hand as I've done here; it just seems like so much work (which I can now confirm.)
