This tree is actually slanted as shown, which I am sure everyone knows is due to the position of the sun relative to where the tree was planted. However, it made me think of how earth art could influence the structure of buildings today. For example, this tree, even though I doubt it, could have influnced the leaning tower of pisa in Italy. In case you did not know it leans because of the poor foundation it was laid upon and the Italians who built it wanted to see what would happen if they kept going ( they also are not known for their architectural skills).
