I have always been fond of guerilla campaigns, especially ones with important messages like this one. The Alex Seo Crisis Campaign brings people's attention to the homeless situation prevalent in many major cities such as New York and London.
Seo brings the issue to light with chalk outlines of bodies coupled with facts regarding homelessness relevant to each urban center. Often, the only way to get people to react to a social problem is to create less-than-favorable images so it will disturb the public enough into at least being conscious of the issue. In that regard, the Alex Seo Crisis Campaign has done a successful job.
