Through the pink and blue vapors of a hot-tub–like installation in a New York City park, you can see how the price of gold is changing.
The hot tub is a temporary art installation called Meridian (Gold), made by sculptor Mika Tajima. It's encased in faux concrete and houses a small, barely foot-deep pool of water with an atomizer that sends up the mist. LEDs in the tub give the mist a magenta or blue tinge. But the color doesn't just change randomly — it's linked to the price of gold.
The piece was commissioned by SculptureCenter, an art museum in Long Island City, Queens, and installed in Hunter's Point South Park in June. Anyone can climb in.
The installation faces the waterfront and gives people a view of Manhattan, one of the biggest financial centers in the world.

The lights are controlled by a computer program that tracks how the price of gold is doing according to several international markets. When the water vapor changes to pink, that means it's trending up; blue means it's going down.

"You’re bathing in the price of gold, basically, while facing one of the biggest financial centers in the world," Tajima tells the Wall Street Journal.
