Jouko Karkkainen has created interesting little box sculptures that are made from different kinds of wood. When you are done looking at the fun little boxes you plant them in the ground and the boxes grow into new trees. Birch boxes grow into birch trees, pine boxes into pine trees and so forth. Art that is life. You can get your own here.

Reminds me of the cellphones you can plant and grow flowers from after you are done with them.
