The relationship between street art and buildings isn’t always happy, sometimes resembling an unhappily-arranged marriage, with only a brief courtship occurring in the middle of the night. But this week, I thought we could look at some happier unions between street art and buildings. Using a kind of sequins for buildings to makes images of glaciers and lava, much of the original wall’s surface is visible. These glittery additions are bright spots in the grey urban fabric and probably a god-send during the winter months when the capital city gets just a few hours of daylight. So maybe a street artist working under the cover of dark would have more hours to work in Reykjavik, but the scale and technical construction that went into these hints at a longer and more symbiotic planning phase.
