What is the best way to say hello to someone -- a wave, a handshake ... a high-five?
California-based tinkerer Andrew Maxwell-Parish believes that of all the gestures, the high-five is king. Unlike "impersonal" handshakes, the greeting is the "quickest and most universal gesture for telling someone, 'you are awesome,'" he writes on Instructables.com.
"The high-five. What a wonderful thing. You can give a random high-five to a stranger and, more than likely, it will make them feel better," he writes in the post, where he also explains how to build the device.
Maxwell-Parish, who runs the innovative Hybrid Lab at the California College of the Arts, designed the high-five camera so that it would automatically start rolling when someone neared with an outstretched arm. The GoPro camera would then cut as soon as the friendly greeting was complete.
