As part of my application for my position at the Cooper Hewitt museum, I built SkyDesigner, a web application that lets users replace the color of the sky with a picture of a similarly-colored object from the Cooper Hewitt’s collection. The “sky” idea comes from the original assignment, which was to create an application using both a weather API and the Cooper Hewitt API, but you can use SkyDesigner to swap out colors from anything you can take a picture of (meaning, it’s great for selfies). Give it a try now!
Here’s how it works: first, users take a picture. If they’re on a computer, they can use their webcam. If they’re on a smartphone, they can use the built-in camera. Android users get (in my opinion) the better experience, because Android supports getUserMedia – this means that users can start their camera and take a picture without ever having to leave the application. iOS doesn’t support getUserMedia yet, so they are sent off to the native iOS camera app to take their picture, which then gets passed back to the browser. Once I receive the picture, I load it into a canvas.
In the next step, users tap on their picture to select a color. The color’s hex code is sent straight to the Cooper-Hewitt API’s search method, where I search for similarly-colored objects that have an associated image. While waiting for a response from the API, I also tell the canvas to make every pixel within range of the selected color become transparent. When I get the image back from the API, I load it in behind the canvas and presto! It shows through where the selected color used to be. Finally, the image is titled based on the object’s creator and your current weather information.
Being a weekend project, there are some missing features – sharing is a big one – but I think it demonstrates the API’s ability to provide fresh, novel ways into a museum’s vast collection. Here’s the link again, and you can also find the source on GitHub.
