Materials matter. Both of these 45-minute films feature the materials as main characters. In Point of Origin, Architect Rem Koolhass used the plasticity of concrete to build a sliver of a house into a hillside, creating his first residential building in 20 years. In veins, we follow massive slabs of marble on their journey from a quarry in Portugal to the exterior of the Perelman Arts Center in NYC. Architect Joshua Ramus (formerly with O.M.A.) works with the natural properties of the material to create a spectacular building where the exterior is graphic in the daylight and glows like a lantern at night.
