A 41-year-old man going by the name of Chibatman rides his “Chibatpod” on the road in Chiba, east of Tokyo, August 31, 2014. The man, who dresses up as the comic book superhero Batman, came up with his moniker after adding a prefix of the first three letters of the city name, of which he roams on his three-wheeled motorcycle. However, unlike the hero from the Batman series, he rides around in his machine, designed from inspiration of the “Batpod” from the movies The Dark Knight and The Dark Knight Rises, delivering smiles instead of fighting crime.

Cuban-American artist Jorge Rodriguez-Gerada's six-acre sand and soil “facescape” stretches across the JFK Hockey Field on the north side of the Reflecting Pool along the National Mall October 1, 2014 in Washington, DC. Titled “Out of Many, One” and composed of 2,500 tons of sand, 800 tons of top soil and eight miles of string, the piece is the artist's interpreative blending of 30 different men's faces. Rodriguez-Gereda used high-precision global positioning satellites to place 10,000 wood pegs as waypoints for the giant face. The piece will be open to the public beginning October 4 and will eventually be tilled back into the earth. (Photo by Chip Somodevilla/Getty Images)

A camel yawns as a tourist checks images on her camera following a ride on a camel safari alongside the Pacific Ocean on Lighthouse Beach, north of Sydney, December 4, 2014. For 25 years camel rides on this beach have given visitors to Australia's holiday coast a rare experience available only in a handful of locations in the country. Australia's long history with the “ships of the desert” goes back to the 1800s when they were imported from Afghanistan and India for use as transportation across Australia's vast deserts before being released into the wild following their replacement by motorised transport.
