For his project Study of Perspective, artist and activist Ai Weiwei took photos of himself flipping off "significant institutions, landmarks and monuments from around the world", notably Tiananmen Square in 1995. Using this Google Street View-enabled web tool, you can use Ai's middle finger to flip off anything you'd like, anywhere in the world.
I've included a few examples above from the site's archive. In a brief review of what folks have done with the site recently, I observed several shots of the Kremlin, the Eiffel Tower, churches, and various Trump buildings, but I also saw the Stonewall Inn and other gay landmarks.
