Street drains are generally pretty dull lets face it! However, thanks to some talented artists around the World, they can be brought to life with a little bit of artistic graffiti. The world’s metropolises are grey enough places without a hard line stance against graffiti – and the good it can bring. Take Sao Paulo, whose sprawling mass is home to almost 20 million people. When street art duo 6EMEIA started painting storm drains in the Barra Funda neighbourhood of Brazil’s largest city, their plan was to transform everyday life in the way only a smile can. 6EMEIA have portrayed everything from animals chomping on their morsels of choice, to a veritable identity parade of other orally fixated mugs and monsters.
