Junkyard Jumbotron: join all your screens into one big one, no software install needed

Here's a demo of the Junkyard Jumbotron, created by Rick Borovoy at MIT's Center for Future Civic Media. It's a cool app to allow you to gang up multiple screens (phones, tablets, flat panels), running any OS, and turn them into a single, joined display. It's very clever: you arrange the screens as desired and then display a web-page with a QR code on each of them; snap a picture and send it back to the server and the server takes any image you feed it and splits it across the screens. No client-side software needed, apart from a browser.

  1. Ok, that QR / photo idea is downright neat. I wonder if that could be adapted for multimonitor desktops somehow?

    1. I’m pretty sure it’d work on any screen that can navigate to a website (watch the vid).

      However I doubt it’d be better than the technology we already have for said activity.

  2. i saw a similar technology at Microsoft Research Asia three years ago. The MSRA required special software, bluetooth, and only worked with pairs of devices if i remember correctly. It did have one feature this doesn’t though. If you were watching a video on one phone, and brought a second phone next to it, the video would automatically span. Separate the phones, and it went back to single screen mode.

    I still don’t know what the point of these things are though.

    1. I think one point is how you can (re)use a few hundred bucks’ worth of old laptops instead of spending thousands of dollars on a single screen…there are lots of places like small storefronts, libraries, etc. where that’s a big enough differenece between having a display and not having one.

      And it also means if a component breaks or is stolen, it can be replaced.

  3. I’m envisioning: a storefront where all the displays are behind the glass. There’s a single point where the glass is cut away and a defunct or broken iphone is rubber-cemented into the hole. Passers by can use the touch interface to control the massive patchwork graphics display. Either for art installation purposes, or to give a ‘junkyard chic’ style to a digital advertisement for the store.

    Very cool stuff.
