A young boy rests by empty USAID vegetable oil tins in the Dagahaley refugee camp which makes up part of the giant Dadaab refugee settlement on July 19, 2011 in Dadaab, Kenya. The refugee camp at Dadaab, located close to the Kenyan border with Somalia, was originally designed in the early 1990s to accommodate 90,000 people but the UN estimates over 4 times as many reside there. The ongoing civil war in Somalia and the worst drought to affect the Horn of Africa in six decades has resulted in an estimated 12 million people whose lives are threatened.

Dutch artist Suzan Drummen‘s large-scale floor installations are mesmerizing and complex circular patterns made out of mirrors and brightly colored glass. The fractal-like arrangements feature ornate and elaborate circles growing exponentially out of each other and vibrant rings of spiraling colors winding into the surface of the floor. They are composed of crystals, chromed metal, precious stones, mirrors and optical glass. A sensory experience, and visually stimulating, the glittering installations play with the architecture of the space — climbing up walls and sweeping across the surfaces — examining the idea of illusion and optical effects.

A busy rush hour sees thousands of commuters climbing on board a train – as well as holding onto its sides and sitting on the roof before it speeds off.
