I have added front and back “covers” to the ePub and PDF versions on the Downloads page. They increase the size of the files, so I’ve left the non-illustrated versions for those people who want to save bandwidth. Don’t expect too much! It’s just me fooling around with GIMP.-)
The front “cover” is from an original photograph by Petr Broz. It’s the same image currently being used as the background for this website, with the color and aspect ratio changed. The back cover is from an original photograph by Richard Thompson. It’s from the same image that was used as the source for the current banner on this website. I hope they make the book a little more friendly and inviting.
