AnyPixel.js
A web-friendly way for anyone to build unusual displays
...To create this installation, we used 5880 off-the-shelf arcade buttons with LEDs inside them as our pixels. AnyPixel.js’ straightforward hardware/software framework makes it easy to build any display where each pixel is an interactive element. We've included 12 example apps written by Googlers and friends for the 8th Avenue lobby display in NYC. To check them out, install the previewer and run one of the examples. Building your own app is easy with the Anypixel framework. To get started, check out the framework documentation and the example app.
