Richard-Box
This happen back in 2004, but it’s still very interesting – thousands of fluorescent lights from the emissions of the cables above–

Hundreds of people are flocking each night for a close-up look at Richard Box’ artistic display of 1301 fluorescent bulbs that are lit by the overhead high-power lines — just from the ambient energy surrounding the lines.

The display, called “Field,” which opened on Feb. 15 and has been extended to March 6, is situated near freeway M4 in Bath, England, where passersby can view the spectacle.
