Erected to highlight an English river's pollution, this 14m-tall metal flower has dozens of LEDs which glow brighter the more the wind around it increases.

Residing by an English river (not the Thames, anglophiles, the Mersey river), it's in aid of a regeneration project to highlight the river's pollution, with the flower not just consisting of roughly hewn pieces of metal—it's actually arranged in the shape of triangles and pentagons, with the center of the flower holding 60 LEDs. Three wind turbines are attached to the stem, which power the LEDs when the wind reaches over 5 miles an hour, glowing more red as the wind picks up speed. [Widnes Waterfront via Dezeen]
