As the introduction (written by me) to A Cats Steampunk Alphabet Book says:
About four years ago, I mentioned on my blog that a steampunk abecedary would be a very cool thing. It started out literally as a joke, a bloggy game of the kind I like to play with my readers from time to time. Except in the real world jokes have a way of taking on a life of their own, mutating and metastasizing into things the originally wiseacre might never recognize.
This thing is goofy, cute and in a weird way, pretty cool. The Buzzfeed post on it shows off the graphics and layout. Me, I’m just highly amused that a project like this could actually come to market, and pleased to see it succeeding.
Check it out.
