In honor of April Fools" Day, take a moment to appreciate this trick of the eye created by the French street artist and photographer who goes by the name JR. He"s known for surreptitiously posting large black-and-white photographs in public locations, often in humorous contexts. This cheeky public-art piece from 2021 was installed in the desert sands of the Giza pyramid complex in Egypt. The installation makes it look as if the detached tip of the Pyramid of Khafre magically hovers above its base.
