Discrepancy is a set of columns positioned according to a grid plan, resembling a concrete column building structure. Metal and glass are incompatible. Cracks emerge under the surface. Sometimes metal and concrete are also incompatible. You might assume force and weight are transferred safely to the ground, but when materials and connections are weak, the grid plan can't save you.
I constructed this unstable environment in response to my childhood hometown, where cracks emerged in what seemed like stable buildings. This happens in other hometowns in the world. Or you watch the news, and see people die in all kinds of cataclysmic events. This shocks at first, but the shock disappears, until the next time.
