Hook up your smartphones and tablets to your computer, and play a game online using them as a remote, in Google Chrome's "Chrome Super Sync Sports." Up to four friends can compete on running, swimming and cycling competitions using one computer screen and their mobile devices. All you need is Chrome installed on those devices, and your computer.
Like many other projects from Google Creative Lab, this one is a Chrome experiment, designed to show off the browser's capabilities, including HTML5 features like WebSockets, Canvas and CSS3.
We saw something similar with B-Reel's holiday card to us late last year -- "Happy Holidays" let you bring animals to life on your computer screen using your phone. Check it out on Creativity-Online.com, and follow @creativitymag on Twitter for more great work.
