Working closely with the creators and stewards of GitHub’s beloved mascot, Mona, we created a deluxe tome, Art of the Octocat, that traces the genesis of this special character and how it has since manifested in all its many forms—2D, 3D, and 4D. The book even includes a page of Octocat stickers for the superfan to affix to their laptop, bike helmet, or any other accessory close at hand. As one of our GitHub collaborators says of the volume, “It’s f**king gorgeous.” (Order one here.)
