German duo of artists called Zonenkinder created an unusual project entitled Tree Project, in which the trees were given life trough painting of faces on their trunks.
The Tree Project was started six years ago. Artists used only very old or broken trees. Moreover, the authors use only biodegradable materials to draw on them. Therefore, the applied damage is very insignificant. Parts of this project are spread in several European countries: Denmark, France and Germany. Over time the pictures fade, and that is disguising them more in their surroundings.
