A handful of decades-old skating venues put Chicago at the center of a vibrant African-American subculture of urban roller skate dancing that stretches from Atlanta to Detroit and from Los Angeles to New York. 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)

“Tiger and Turtle–Magic Mountain” by German art duo Heike Mutter and Ulrich Genth is a walkable sculpture shaped like a roller coaster. Visitors can stroll along the track (except for the loop sections). The 69 foot tall sculpture is located in Wanheim Duisburg, Germany.

Throughout time, people invented and reinvented rollerblades. Of course everyone’s dream was to combine them with regular footwear, so that at one moment you’re riding down the road, and in 5 seconds you’re walking into a shopping mall, without the mall cop chasing after you. The most resent inventions were heelys (sneakers with a wheel located in the heels) and Xsjados (aggressive skates, the exterior of which could be removed to reveal regular sneakers). In the past, people made similar attempts, however, these inventions were very inefficient and the trend never caught on. Omnia’C has found and made photos of one of such inventions: pop out roller skate sandals all the way from 1970s. Though their design is pretty cool, it seems like they would be very uncomfortable, since they totally lack ankle support.

This artwork created using the end of a drill is the work of Swiss photographer Fabian Oefner who captures the flight of paint in just one 40,000th of a second. His latest Black Hole series celebrates the physics of centripetal force and the effects it has on simple paint and a an ordinary drill with a metal rod connected on the end. The incredible result of Fabians work comes out looking like a picture taken on the Hubble Telescope of some cosmic event. (Photo by Fabian Oefner/Caters News)
