This is an honest-to-God real and oversized coffee mug. But one side of the mug is flat and has an augmented reality marker. Download the app, launch it and point the camera on your iPhone or iPad at the marker, and it changes on the screen into a basketball hoop. You can now shoot hoops while you’re on a coffee break. Be warned that it’s a whole lot of fun, and you’ll end up slam-dunking balls when you should be studying or working.
