There have been several examples of heat-giving bus shelters recently, from the likes of Coca-Cola in Sweden and the Greater Fort Lauderdale Convention & Visitors Bureau in New York. However, this is the first time we've seen it done for a charitable reason. Last autumn, the homeless people in Vienna's City Park were evicted. So charity Caritas decided to help. Agency DDB Tribal Vienna created an adshel that gave off heat every time someone put in one Euro. The idea was to raise awareness of the charity's work, and show that even a small contribution can make a difference. The slogan on the heated bars of the shelter translates as "Give Warmth."
