This anti-smoking poster campaign from the Russian Ministry of Health has an interactive element that encourages people to check in on Foursquare at places that ban smoking.

BBDO Moscow designed the series of posters, each with a damning diagnosis printed in a search box shaped like a cigarette. Each poster carries a QR-code leading to a Foursquare page where users can check-in at 10 nearest "No Smoking" places in Moscow.

According to Russian Ministry of Health, smoking kills 400,000 Russians every year. New laws banning smoking in certain places came into effect this summer.
