Pair of scissors
Graffiti of a pair of scissors cutting a white dotted line is a simple solution to a long-time debated problem. Removal of the Matilija Dam in Ventura County in California was proposed in 1998. Since then, the county has offered many time-consuming and costly removal solutions, but nobody thought about art. The painting is not a simple art creation.
The artist had to come down with the zipline to paint the dotted line on the face of a 200-foot tall wall. The anonymous artwork is very clever, bringing humor to serious debate that great minds did not solve for years. Beyond the art, the government rebuilt two bridges and created holes in the bottom of the dam to encourage the water flow.
