Triangles are the most reliable and stable shapes in architecture. Their use dates back longer than other construction shapes like the dome, arch, cylinder, and even the wheel. Stripped of outer skin and context, they make building blocks that are delicate sculptures of ethereal beauty, grace, utility… and dread. Their inherent strength forms the ubiquitous skeletons of our technology, power and communications. As such they are harbingers of advancing civilization, with its modern amenities and conveniences, but also ominous totems of surveillance and the desecration of the landscape. These structures are x-rays of our culture.
