Also treehouses can smile!
This treeehouse is situated in Rapperswil (St. Gallen, Switzerland). The kids and owners of this treehouse transformed one of the fourth facade of the treehouse in a face. with a LED lights draw the eyes, the mouth and the nose on a branch, meanwhile the others branches have the function of hairs.
I guess that in the night this treehouse would have a face of Pinocchio!
A new and creative way to give a touch of personality to an inanimate object.
