NSKYC is an online project which aims to map the color of the sky above New York City. Why? Because Mike Bodge, the man behind the initiative, wonders how the average color of the New York sky looks like. NSKYC shows a large collection of webcam images of the Manhattan skyline and sky, updated with a new picture every five minutes. The website derives an HTML color code from every webcam image that determines the average color of the sky, and contributes to the analysis of the average sky of New York City in general. Bodge has also made available a Washington version, and I think that more cities will follow since he actively invites others to join his project and map their own cities. Check it out!
