TapTap is a wristband that pairs with another TapTap wristband to bring you and a loved one closer together. You tap-tap your TapTap, and your special friend feels a gentle vibration in the paired wristband, wherever in the world the two of you may be. But that's just the Kickstarter bait. The real potential of TapTap lies in its accelerometer and gyroscope in combination with the API. Listen up, developers.
