MC Hammerheadshark uploaded to his Flickr this image of the Sarajevo Rose (wiki). He tells the Wooster Collective:
"As I was passing through Sarajevo I couldn't help but notice the effects of the Bosnian War. It's everywhere, in the buildings, in the people, in the graveyards that stretch blocks and blocks. But the most impactful of these markings are on the street. While walking the city you are sure to come across a splattering pattern of pock-marks from where a mortar round hit.
To signify places of significant deaths, the explosion marks are filled in with red resin to create the Sarajevo Rose."
