MIT’s SENSEable City Lab is working on Flyfire, tiny robotic flyers with different colored LEDs that will be able to make images while hovering in the air. The flyers will be able to self-organize, acting as “smart pixels” to form complex shapes in space.
“”The Flyfire canvas can transform itself from one shape to another or morph a two-dimensional photographic image into an articulated shape.”
The movie below shows a few of the flyers, as well as simulations of what a full flock of Flyfire robots might be capable of.

Wow – almost like smart dust!
