Tennis season is coming, and what better way to celebrate the sport than by playing it on your wrist? That's the idea behind A Tiny Game of Pong, a version of the Atari classic designed to run on the Apple Watch. It was created by developer Matt Wiechec in order to learn how to design apps for the wearable. Once installed, you can use the watch's digital crown to push your paddle back-and-forth across the display. Should you wish, you can also switch the theme colors from black and white to match those of your strap.
