Millions — perhaps tens of millions — of shipping containers are sitting empty at ports all over the world. And they've been a treasure trove for architects Ada Tolla and Giuseppe Lignano.
"We found so many — it felt like something so ripe to pick, basically," said Lignano. He and Tolla were in San Francisco recently for the opening of an art exhibition at Hosfelt Gallery focused on their use of shipping containers as building material and art project.
