I think this is pretty cool for couples that are staying true to a long distance relationship. The Hey Bracelet allows you to reach out and "touch" your sweetie no matter where you are in the world. It's connected to an app on your phone, and when activated, the bracelet gives your partner a gentle squeeze so they know you're thinking about them. It's in the Kickstarter phase if you want to get in early, or wait it out to see if it really works.
Someone needs to invent a bracelet that painfully zaps me when it senses I'm about to shove an entire sleeve of Oreo cookies down my throat. Now that's incentive!
