Here it is--the answer to yesterday's location stumper. It's called the Sonoran Pentapus Pavilion--located on the west side of the university's College of Architecture, Planning, and Landscape Architecture. It's a type of structure called a "gridshell," which I know nothing about, and it was hand-built by University of Arizona architecture students in the sweltering Tucson sun. You can read about it here.
UA architecture professor Chris Trumble said that it was a tough location for the students to tackle, with "terrible lighting" from the west-facing architecture building--which would explain my sun-deficient photo.
Fun fact: it was funded by Canada. Why? Because the Land of Moose and Maple Syrup gets it.
