As a sign of love to the world, a group of antiwar protestors (or peace promotors) joined together to form an all-human, all-nude peace symbol on Valentine's Day, 2003. The spectacle was unspectacular. Despite the local law prohibiting nudity in the park (minimum requirement of thong and, for women, a bikini top), the police allowed the display, but only behind opaque barriers. The audacious protestors did leave a mark at the courthouse on, of all things, attorney's fees. Check out the Supreme Court case of Sole v. Wyner, 127 S. Ct. 2188.
"But the display was set up outside the barrier, and participants, once disassembled from the peace symbol formation, went into the water in the nude." Sole v. Wyner, 127 S. Ct. 2188, 2193 (2007).
