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)
