The Kindness Rocks Project
The Kindness Rocks Project is a viral trend where people, commonly children, paint pebbles or cobbles and leave them for others to find and collect. Photos of the painted rocks and hints of where to find them are commonly shared on Facebook groups. The trend originated in the U.S. and has spread to the other countries, including U.K., Australia, New Zealand, and Haiti.
Similar projects include happy stones and doodle stones, which are often grouped under the term Stoones as a collective term for traveling stones.
