Automatically Created Unique Bookcovers

Publisher Faber & Faber is using POD to their artistic advantage: every individual book is printed with a unique cover design, originating from the book's genre, but randomly assembling beyond that point.
While I consider them rather bland, compared to other mass-reprinter who does generic, crappy covers for everything (I'm looking at you Kessinger), it's unique and eye-catching without the publisher having to put a lot of effort into it. (via)
