Kartik Thakore and the other SDL Perl hackers have a guide to multimedia programming and game development with Perl underway. We will have part of this book available for your perusal at YAPC::NA 2011.
As is our habit, we're writing and editing these books in public. You're welcome to read along as we produce them, suggest new areas, fix bugs, and spread the word. We'll continue our very liberal redistribution policy as well when we reach the printed page.
(Moose fans do not despair! Lock some combination of Stevan Little, Chris Prather, Dave Rolsky, and myself in a room for an hour with the appropriate libations and we'll see what we can do.)
