The Hobbit: The Desolation of Smaug will hit theaters in less than two weeks, and Googles not the only tech company taking part in build-up to the next Middle-earth film. Microsoft announced a partnership with Warner Bros. UK thatll bring some interactive ads to Windows 8 apps and eventually across the MSN and the Xbox 360. Its a fun idea, albeit one that only a small number of 3D printing and Tolkien enthusiasts will likely take advantage of — but its also an idea that could become increasingly commonplace. However, the Microsoft / Warner Bros. partnership takes it a step further, letting fans download the blueprint directly and print it anywhere they want — including their own 3D printers.
