In any case, birds make city living a bit more interesting with their presence, something that Brazilian street artist L7m would most likely agree with, as seen in his vibrant murals of larger-than-life birds that liven up dull urban landscapes. Seen over at This Is Colossal, these wall paintings by L7m (also known as Luis Seven Martins) are part of his continuing experimentation combining media like china ink, latex, pastel and acrylic with traditional spray paint. L7m/Duncan C via Flickr/CC BY-NC 2.0Martins began working with spray paints at the age of thirteen. He has since developed a distinct style that combines natural themes with colourful, freeform geometric abstractions, inspired by what he calls "the revolt by human sorrow, the beauty of life, the city’s disarray, [its] neglect and surroundings." These flourishes of lines and colours seen in these birds seem to suggest a kind of energetic chaos, harkening to a universal source of creation, or breaking life down to its immaterial essence. Martins also uses real feathers in adding stencilled accents to his works -- a creative touch. Martin's murals seem dreamlike and mythical on one level, and yet are grounded in the urban landscape by the tumultuous lines that surround them -- as if the natural world can be balanced with this human-made chaos, and adding an extra dimension to our sometimes drab cities.
