<h3><big>SHOPPING CART TREE</big></h3> In a tower of glistening metal and lights, the <a href="http://inhabitat.com/towering-christmas-tree-made-of-86-shopping-carts/">Shopping Cart Tree</a> is an awe inspiring alternative to the evergreen tree.

Schmitt has been building cart trees for fourteen years and says that they "symbolizes both generosity and abundance, as well as acknowledging those less fortunate where their whole world may be housed in a cart. We see shopping carts everyday and take them for granted. Individually the beauty of an everyday object may become invisible, but in quantity you can’t miss it".
