It’s not often you see a demo that blows you away both with the technology and the possibilities. This project, the Junkyard Jumbotron from chris csik aims to easily enable a group of screens to display one complete image. A user navigates each device to a unique url, this displays a 2d-code on each of the screens, you snap a photo of the codes to capture the configuration and a web server calculates how to slice and display the image, it can even be manipulated from the devices in near real-time. Just wow. 

On Vimeo, via Gizmodo [via BoingBoing].

The codes are not QR codes like Gizmodo states, but they are a form of 2d-code and the technology and use is incredible, so it falls well within the banner of blackandwhitesquares.com
