Baptiste Debombourg (previously) has transformed a public square using the very objects that typically occupy it—taking 1,200 café chairs and forming them into an elaborate roller coaster. Although the installation is static, Debombourg created movement within the sculpture by incorporating six bright colors and four sky-high loops that twist and turn far from the ground.

The installation, titled Stellar, was built as a part of Le Voyage à Nantes, and will be located within the Place du Bouffay in Nantes, France until August 20th. Its inspiration stems from addressing the great presence of outdoor cafés and restaurants within the city center, as well as an artwork Robert Delaunay produced for the Paris World’s Fair in 1937. (via Junk Culture)
