Without fail, CES always manages offers up something a little unusual alongside the halls (upon halls) of TVs, tablets and home appliances. In fact, it's the weird things that often catch our attention the most. So, what about Belty the smart belt? The name alone screams "offbeat," but it's the way the wearable pulls it all off that caught our eye. It not only adjusts for your waist automatically (the cool part), but also offers up metric data... and associated health warnings, if needed. We present the Best of CES 2015 Offbeat winner. Marty McFly would probably wear one.
