MIT researchers are exploring whether a swarm of tiny helicopters outfitted with LEDs could self-organize into a massive flying display "screen." The vision for the nascent Flyfire project is that each of the choppers acts as a pixel to form a dynamically-reconfigurable display.
From MIT's SENSEable City Lab, co-developers of the Flyrire project:
With the self-stabilizing and precise controlling technology from the ARES Lab, the motion of the pixels is adaptable in real time. The Flyfire canvas can transform itself from one shape to another or morph a two-dimensional photographic image into an articulated shape. The pixels are physically engaged in transitioning images from one state to another, which allows the Flyfire canvas to demonstrate a spatially animated viewing experience.Flyfire
Flyfire serves as an initial step to explore and imagine the possibilities of this free-form display: a swarm of pixels in a space.
