A Smartphone Turns These Fast Food Trays Into Tiny Soccer Fields

Decades ago McDonald's realized that food wasn't the only way to draw kids into its restaurants. Toys, playgrounds, and cartoon characters all help the cause, and now a Brazilian food chain called Giraffas has come up with a clever way to lure soccer fans into its restaurants, just in time for the 2014 FIFA World Cup.

After downloading a free app, you can prop your smartphone up on its side on one end of the serving tray, allowing its front-facing camera to detect the soccer field graphics on the paper insert. Folded paper balls are torn off the edge of the placemat, and can actually be flicked at a virtual on-screen goalie, with the camera detecting their motion and determining whether a goal has been scored.

Do you want fries with that? No, but a few thousand screaming supportive fans wouldn't hurt. [YouTube via DamnGeeky]
