If you walk around town or country, you may have found a piece of artwork in the form of a painted rock. Sometimes they have an encouraging statement on them, other times a colorful image that brings a smile and sense of gratification.

"The best part about painting rocks is putting these small pieces of art out into the world to share with others as an act of kindness," says Ashly Beebe of Dayton.

"I have found a few rocks myself, and it is such a special moment. For some it's a smile, and for others it's what they needed on a bad day or a reminder of a loved one."
