The display was created using modular components so its size and shape can be changed at any time. The LEDs, which cycle through different Google typefaces, were arranged on a 140x42 canvas at the company's 8th Avenue office.
Analog switches are particularly difficult to program when compared to digital, so Google created open-source code to allow builders to use analog components where each pixel is an interactive element.
The software is called anypixel.js, a tool that makes it possible to create interactive displays out of anything "touchable, toggleable, flippable, or switchable." Google's Creative Lab website says builders can use a wall of light switches, lightboxes or even balloons with anypixel.js to create their own interactive display.
The lobby of Google's 8th Avenue New York City office is open to the public, so you might try to get your eyes and hands on it if you are in the area. Everyone else who knows how to draw on an HTML canvas element can start making their own crazy displays with anypixel.js and whatever hardware they have lying around.
