Re-think big screens. Really big screens in the sky. Think swarms.

MIT’s Flyfire project uses a swarm of miniature helicopters with embedded LED lights to act as ’smart pixels’ as they fly through the air. Acting in concert they will be able to form complex three dimensional shapes – digital displays that will awe you more than exploding chemicals ever could. Not only will the pixels change color, the 3D dynamic movement will create an immersive experience that you can view from any angle.

I was just reading a Trends Magazine article about the new CEO of Barco, once – and to be honest still – of the pearls of the Flemish tech industry.

Have a look at their history here. They started in 1934 as a company specializing in the assembly of radios with parts from the United States. Hence the name, "Belgian American Radio Corporation" or Barco.

Now, in 2010, they are a global leader designing and developing visualization solutions for a variety of selected professional markets. They are big in events and shows: The world’s major bands use Barco lighting, projection and LED technology, e.g. U2, Depeche Mode, Bloc Party, Coldplay or The Prodigy

Imagine Barco implementing this new MIT Flyswarm technology and scale it so that it can be used as a massive projection-in-the-sky for the next U2-tour !
