This is awesome.

This field has 1,301 florescent bulbs planted in it, and they’re all glowing. They aren’t plugged into anything, however; they’re powered solely from the magnetic fields produced by the power lines above

I’ve done this myself, with a single bulb. There’s nothing to it. Take a fluorescent light, walk under high-tension powerline. Voila! (Residential ones don’t work.) But what that artist has created looks like some extraterrestrial art installation.
