This site? Is great.
When the merger of Random House and Penguin was approved, it was clear to all that the new company needed to be called Random Penguin. Well, perhaps not to all. That the executives in charge decided to call it Penguin Random House instead just proves that their souls had withered some decades past. One lone protester decided to demonstrate against this great nomenclatural wrong by putting random penguins into the covers of books issued by Penguin or Random House. The results are great -- check 'em out.
I particularly like Mists of Avalon and Throne of the Crescent Moon. :D
(Note that they're taking submissions, too, so if you feel inspired, fire up Photoshop make with the random penguins.)
