Radical artist Ai Wei Wei just finished his latest project, and this time it’s an unmissable installation on the Konzerthaus columns in Berlin. For the last several months, he has been working from the Greek island of Lesvos, documenting the thousands of Syrian refugees that arrive on its shores after battling a harsh journey in the incredibly dangerous open waters. After his experience, he shifted his sights to Berlin and created something that draws a huge amount of attention to the humanitarian crisis happening in Syria and the countries the refugees flee to. Using about 14,000 orange life jackets, the artist wrapped them around six pillars in front of the Konzerthaus, in an effort to show people just how many lives are affected by the crisis.
