If we’re going to be killed by swarming robots, they might as well look good doing it. Scientists at the MIT SENSEable City lab created a 3D display using tiny remote controlled helicopters that float in patterns in the air and light up, thereby creating a volumetric display.
Called the Flyfire, it seems that this is either still in concept stages or they’ve gotten it to work in limited situations. Obviously these little helicopters are really hard to fly but presumably you could do this fairly easily in a closed room – although propeller interference could be an issue.
