A new art installation in New York’s East River brings glamour to the science of water quality! The 50-foot-by-50-foot floating sculpture – shaped as a plus sign – lights up at night. The lights then change color to indicate whether the water is clean. Titled “Plus Pool Light,” the physical sculpture incorporates real-time data every 15 minutes to indicate actual water quality.

“We wanted to create a way for the public to visualize water quality data,” Kara Meyer, the managing director of Friends of Plus Pool, told CBS News.

Most of the data is collected in the water around Manhattan and input to determine the lights’ color happens every 15 minutes. All of the data collected is available to the public here.
