Tecotosh, Steel and glass sculpture at Portland State University, US

Tecotosh is an outdoor abstract sculpture by Ed Carpenter, installed in 2005–2006 outside the Maseeh College of Engineering and Computer Science at Southwest 4th and College on the Portland State University campus. It is built from a stainless steel truss, cables, hardware, laminated dichroic glass and lights.

Tecotosh was made in 2005–2006 to a design by Portland artist Ed Carpenter. The Smithsonian Institution records the Northwest Center for Engineering, Science and Technology, the building it stands beside, as the owner of the work. It was installed on the Portland State University campus at Southwest 4th and College.

The name is not explained in the sources; the work is titled Tecotosh and signed by Ed Carpenter. It stands where engineering students pass daily, outside the Maseeh College of Engineering and Computer Science, so the artwork is seen in the routine of classes and campus walks rather than in a museum setting.

The sculpture sits outdoors in a freely accessible location at the building entrance. You can view it from different angles throughout the day and night, as the integrated lights highlight the glass elements after dark.

The dichroic glass elements shift in appearance based on the angle of light and time of day. This means the sculpture looks different depending on when you visit and where you stand around it.
