Above is Driftwood aka Petra, a summer pavillion installed in Bedford Square, London UK in 2009. The concept was designed by third-year architecture student Danecia Sibingo, with a design team of Lyn Hayek, Yoojin Kim, and Taeyoung Lee. Twenty-eight layers of plywood sheath a hidden structure. Driftwood seduces viewers to walk around and through it, inviting us to examine its strata. It reminds me of the friendly Cloud Gate sculpture by Anish Kapoor in Chicago's Millennium Park.
