Plague Inc.
Of course I would have to show an app on this site. Not just an app but a strategy genre game. It's called Plague Inc. available on iTunes. A fairly simple premise of working with a virus, bacteria, etc. to infect the world. This game can be very addicting but if you want to really feel like you're in a sci-fi movie use AirPlay to put it on your big screen TV. Click on the image below for the link.
