Christo - "The Floating Piers"

For 16 days, “The Floating Piers,” a saffron-colored walkway, will connect two small islands in a lake in Northern Italy to the mainland.

“It’s actually very painterly, like an abstract painting, but it will change all the time,” Christo, 81, a Bulgarian-born American, said of his project.

"Getting the walkway to both gently undulate and remain securely affixed to the uneven lake bottom was a feat that has occupied engineers, construction companies, French deep-sea divers and even a team of Bulgarian athletes drafted over the past two years. The walkway is assembled from 220,000 high-density polyethylene cubes that form its 16-meter-wide (53 feet) spine, covered this week with a waterproof and stain-resistant fabric made by a German company for the project."
