On Stanford Campus we used to have an intersection called "The Intersection of Death" which was a 4 way mostly blind bike-only intersection of two major bike routes. In the middle of the night the trumpet section of the marching band erected a roundabout in the center of it complete with signs explaining which way to go. amazingly a week later it was still there and someone replaced the half-assed trumpet player statue they had erected with a cool abstract pvc sculpture. A few weeks later someone else added to it. The roundabout was guerrilla installed in fall and the university left it standing until the next summer when they tore it out and put a permanent cement one in.
