The travelling gnome (also known as the roaming gnome or gnoming) is when someone brings a garden gnome lawn ornament on a trip and takes pictures of it in front of famous landmarks. Some instances became national and international news stories, where people have stolen a garden gnome from a garden, and then send the owner photos of the gnome for a period of time as a practical joke, before returning it.
The Garden Gnome Liberation Front in France is a community that considers gnoming to be stealing garden gnomes from other people's property, without the intention of returning them, as part of their purported mission to "free" gnomes and "return them to the wild", which has sometimes led to criminal charges, jail time, or fines.
