Defenestration

I crossed Howard Street in San Francisco and looked up at the signs that had pictures of the world's strangest married couple and saw benches that looked to be crawling across the face of the building, chairs sliding down walls, tables leaping out of windows, lamps twisting themselves towards the sun, bath-tubs and fridges sticking halfway out of windows, ready to fall, and a sofa balancing precariously on the roof.

Weird California explains: "It's actually a sculptural mural called Defenestration, and was conceived and created by California artist Brian Goggin and one hundred volunteers".
