    Some psychologists say that community art — art made to be displayed free of charge in a particular community — can make a big difference.

Unlike the random graffiti （涂鸦）that many people consider an eyesore, community art can bring people together and encourage respect. In the U.S. city of Philadelphia, for example, psychologists are doing a citywide project where mental health patients work with average people to paint murals（壁画）. The aim of this project is to reduce the mental illness and promote a new dialogue about people who struggle with these issues.

Art also makes neighborhoods more attractive and has a unique ability to open people up. Neighbors can share comments with one another about a recently painted mural, which can challenge their prejudices and open their eyes to the world.

Businesses can also be promoted by community art. In Fort Smith, a town in the U.S. state of Arkansas, artists from around the globe came together to paint murals. One of the goals of the project was to expand the town's cultural offerings in order to attract more visitors. Not only locals but also tourists were drawn to see the murals. The money they spent while visiting the town benefited local businesses.

Generous financial support is provided for community art projects in many cities and towns. In the UK, the Arts Council England has invested nearly half a million dollars in community art. Some of it, for example, has paid for a new exhibition space created inside an old mill in the town of Brierfield. In the U.S., an organization called the Knight Foundation has invested millions of dollars in community projects, including many that focus on art.
