Typically, you've got an artist on stage singing songs and stuff, and then a bunch of spotlights beaming columns of color through some fake smoke. But something new is on the horizon, and it's equal parts creepy and futuristic. Swarms of artificially intelligent drones are starting to show up on stages around the world.

Others, like a recent Cirque du Soleil experience, featured more complex aircraft outfitted with lampshades that produced an almost ghostly effect.
