Going out to socialize isn’t the same as it was even a decade ago. With smartphones and social media, most people out in the bar or the club have their phone up the whole time to check messages or take pictures, not notice the people around them. Firefly is a wearable LED band that checks messages and sends out Facebook profiles and common interests, lighting up with a specific pattern if someone else in the area has similar interests, allowing them to meet and talk face to face. In terms of design and functionality, the Firefly is similar to Wave, but adds the pivotal local matchmaking element. Firefly will hit the town in October and is available for $69.
