French artist Thomas Lamadieu, also know as Roots Art, must really love looking at the sky. Every time he looks up, Thomas sees a potential canvas where the building rooftops frame the sky. He photographs it and uses the odd sky shapes to create whimsical line drawings. “My artistic aim is to show a different perception of urban architecture and the everyday environment around us, what we can construct with a boundless imagination,” says Thomas.

“A British photographer has captured incredible images of Italys most beautiful derelict buildings – by sneaking into abandoned structures. The stunning shots of hospitals, churchs and deserted buildings show abandoned beds, overgrown arches and staggering staircases. Gaz Mather, 40, is a dedicated urban explorer who takes stunning photographs of deserted buildings – documenting their haunting decay. Gaz from Manchester spent a long weekend touring deserted buildings in the Northern region of Italy”. – Caters News. Photo: Abandoned Villa. (Photo by Gaz Mather/Cater News)

A woman wears roller skates with lights on the bottom at Rich City Skate in Richton Park, Illinois, January 12, 2015.

While mainstream roller skating has been on a long decline, a new generation of skaters travel a circuit of rinks around the country to compete and show off their moves. (Photo by Jim Young/Reuters)

Ralph Mirebs, an urban explorer and photographer in Russia, has revealed extraordinary photos of Soviet space shuttle prototypes gathering dust in an abandoned hangar. The abandoned hangar is located at the Baikonur Cosmodrome in Kazakhstan, which is still in operation today (with the close of NASA’s shuttle program, Russian Soyuz shuttles are the only way for astronauts to reach the International Space Station). The Buran prototype shuttles found by Mirebs, however, are from an earlier era – they are the last remnants of a space program that began in 1974 and was finally shuttered in 1993.
