Walkers find stones marked with postal codes. What do they mean and why is it worth photographing them?

A colorful stone painting initiative has gained popularity in Poland, originating from the Czech Republic. Participants paint stones and leave them in various locations for others to find, photograph, and either keep or relocate. Each stone typically features a colorful design and includes information such as a postal code and a Facebook group name. The activity encourages creativity and community engagement while promoting environmental awareness. Participants are advised to use eco-friendly materials and ensure stones are left in safe locations, avoiding personal information on the stones.
