Here's a very cool demonstration of an augmented reality app, which is sure to delight fans of the Alien franchise. Simply install the free app (iOS, Google Play), print the target image (or buy an official T-shirt), and you can film a friend with a nasty chestbuster xenomorph protruding from their body. Or wherever you like! I recommend a sleeping pet. Brought to you by the talented folk at Fingerfunk.
