This Digital Installation from Yahoo! is a pretty cool way to light up the reception area for the head office in San Francisco. It’s based off a new 3D gesture controlled system that allows passers by to interact and control Yahoo! branded content through body gestures and movement that aims to mimic natural human responses. The brief to Tronic / Brandfirst from Goodby, Silverstein & Partners also made note there was to be no instructions or screen prompts, as they wanted people to experience the response patterns by accident. Pretty cool, but could have been taken further?
