Clay Lipsky has created a great series called Atomic Overlook. The project takes terribly boring scenic shots and combines them with some exciting nuclear testing. “Tourists will line up for anything and I always found humor in vacation destinations that are nothing but a bunch of people looking into a great abyss”, he says. “I understand the allure of a beautiful landscape, but as the world’s population grows so do the lines to view the “nothingness”. Atomic Overlook flips the script on that and gives new purpose to those suntanned masses”. (Photo by Clay Lipsky)
