I cannot say that I 100% understand what the people of JPG Magazine had in mind when they came up with this theme, but I submitted this photograph. This is a theme for the next issue of JPG Mag and is sponsored by Adobe. That means besides money and a free magazine subscription, there are also Adobe software packages for the lucky ones who make it.
The image shows alternately concave and convex bent windows reflecting and distorting another building. I photographed this in Downtown LA two years ago.
