Here (sorry for the Vimeo) is video of a random book vending machine installed in the Monkey's Paw bookshop in Toronto:

I would lose so much money to one of these machines if someone in Seattle made one. (Incidentally, I was surprised to note that I have read one of the books in this video: Lawrence Welk's autobiography, Wunnerful, Wunnerful! I was turned on to Welk's particular blend of literary insanity by Lisa Carver's book Dancing Queen, and it really lived up her hype. If you're looking for a bizarre celebrity memoir, it doesn't get much better than Welk's books, which espouse the glory of naps and rail against America's unfair child labor laws.)
