Remote Control Helicopter Swarm "Fireworks" Display

Dozens of remote control helicopters programmed to fly in various patterns that trail below them a long string of very bright flares of various colors. These flares are ignited at pre-determined times when the helicopter is at the correct position and time for the particular animation pixel to be shown.

Some animations might include:

A dolphin made of "stars" swimming across the sky.

A standard fireworks explosion but in slow motion.

A mile wide spiral that would make the whole audience feel like the world is spinning.

Flying to the various constellations and highlighting them.

Multiple "stars" flying at the audience giving the effect that they're accelerating through space, a-la when they enter warp speed in science fiction. (Star Wars, Star Trek, etc)

Of course just flying into particular shapes and flying apart into different shapes, perhaps with a narration over the loud speakers telling a story.
