Structure Systems by Heino Engel “This book is kind of like a little bible that I found – a friend who went to architecture school had it on his coffee table, and I thought it was amazing. It’s about airplane hangers and other large spans of material that do things, and how wind and earthquakes can affect them, and as soon as I brought it to my studio, we all learned from it. We started reading about how things become strong, and how strength plays into the material you’re using, and began trying to figure out how can we use clay to emulate that.”
