It had been merely an electrical tower: a functional work engineering. Then art students from Klasse Löbbert transformed this tower in Essen, Germany into a wonder of light and color. Ail Hwang, Hae-Ryan Jeong, and Chung-Ki Park call their work Leuchtturm, which means Lighthouse. The color comes from sheets of acrylglas. You can see more pictures of it at Colossal.
