Few things are more beautiful than puffy white clouds floating in the bright blue sky. Do you remember the time when you would lay on the soft green grass, look up at the sky, and try to recognize shapes in the clouds floating overhead? Wasn’t it wonderful, just lying there, letting the wind caress your skin, as you imagine that the clouds in the sky are actually mystical or not-so-mystical creatures? Dragons, ducks, teddy bears, dinosaurs, everything was up there. It was good old times. As adults we forget about simple pleasures of life. However, an Argentinian artist Martin Feijoo didn’t forget those times, and took them a step further. After imagining what a particular cloud looks like, he draws that particular shape over the picture of the cloud, allowing the entire world to see what goes on in his mind. (Photo by Martin Feijoo)

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)
