It’s only a glow in the dark skate park!!!1!!11!
Otro is a skateable sculpture located in Vassivière Island, France by Korean artist Koo Jeong-A. It is designed to extend skating hours past daylight by being a glow in the dark structure.
The structure, which is set against a backdrop of trees, is made of green phosphorescent concrete and is comprised of deep ovoid forms that are connected by tunnels, successfully combining a beautiful form that is also practical.
