Zagreb’s credibility as a city of outdoor artistic expression has increased dramatically over the last several years, in part thanks to a group of young, loosely affiliated artists called MUU (Museum of Street Art) and their scattered collections of murals around the capital. The most prolific of these artists is OKO (“The Eye”). Her phantasmagorical images of humans with birds’ faces, or dreamy patterns woven from what look like entrails, are decorative and disturbing in equal measure. “The bird-faces are a symbol of freedom, of something pure,” says OKO. “I read somewhere that birds are carriers of the soul after death, and I was really inspired by that idea.” Stuck to surfaces throughout the city, OKO’s pictures look like prints or photocopies; they are in fact painted on thin paper with acrylics before being glued to the wall of her choice. Her trademark larger-than-life human figures with animal heads can be seen at Zagreb’s Museum of Contemporary Art, decorating the courtyard of Medika club and at the outdoor wall of the &TD theatre bar.
