Electrical field glow jewelry

Fluorescent lights will glow in an electrical field. It is possible to light a bulb in your hand if you are near a high power line, just from the excess thrown off by the lines. I propose to harness this effect for club dancefloor jewelry.

People on the dance floor would wear jewelry full of mercury vapor - essentially fluorescent bulbs. I envision these as large: multistranded necklaces, bracelets, anklets, belts, harnesses, whatever. The jewelry would be inert most of the time. On the dance floor, hidden machines sweep and pulse the area with electromagnetic radiation, causing the jewelry on all dancers to light up and pulse in synchrony with each other.

Other glow tubes and structures in the floor, pillars, and ceiling would also glow and flicker along with the dancers.

In a dark room, it might be possible to lose the effect of people in a crowded room, and instead see only the light effects. I wonder if it would be possible to sculpt the broadcasted electric fields such that different tubes and structures in the room lit up to form pictures? Jewelried dancers positioned between objects would become part of the picture. This picture would not be static, but could actually move and change by varying the broadcast field. You could make it look as though giant glowing lions were rampaging about the dance floor.
