I've had the pleasure of working with remarkable people, one of whom is a psychiatrist. To show my gratitude, I've crafted a DIY Book Clock using the DSM-IV Guidebook, which is a clinical bible in the helping profession.
The project required a bit of elbow grease along with clock hardware, drill, X-acto knife, picture hanging hook, some glue and a hardcover book.
The burlap bag has great step by step instructions. I added a few of my own; glued the pages together and added a hook on the back of the book so it can hang easily.
