You met on Tinder, you romanced on Snapchat, and now your smartphone can also help you to get physical. (No, not in that way, pervert.) An iPhone game called Bounden has just arrived at the App Store and it's designed (in partnership with a ballet company, no less) to instruct you on how to make beautiful shapes with another person. As demonstrated in the video below, you both hold onto the phone and then try to move some gyro-responsive dots around the screen. Get it right, and you end up with some nice twirls, a high score and a partner for life. All for $4.
