This image originally comes from cowbirdsinlove.com but sadly it seems the page that once showed it is no longer there. I saved it from that site already back in 2015, but I cannot recall the exact URL it used. The image is still available at https://cowbirdsinlove.com/comics/base10.png.
Since I consider this picture such an iconic classic and masterpiece, I decided I better host it here in a small attempt to preserve it for everyone to enjoy.
Because, you know, every base is base 10.
Update: the original page on archive.org.
