Cambridge-based public artists Mags Harries and Lajos Héder are the brains behind a solar-powered art installation in Austin, Texas. The flower-like solar panels soak up the sun’s rays by day, and give off colored LED light by night, according to Popular Science.

“Designed by Massachusetts art duo Harries/Heder, the SunFlowers are an art exhibit at heart, and stand over 30 feet tall. They collect power from the sun by day, and use that energy to power their blue LEDs at night. Up to 15 kilowatts of surplus power is sent back to the grid as payment for any maintenance fees the SunFlowers incur.”

The art duo also designed 300 Summer St., an artists building, and the Man from City Hall, a First Night exhibit from 1989 I’m not sure I believe really happened.
