I've had this terrible flu this week and don't feel like rejoicing in nature (or in much of anything, save Jell-O). Here's the completely gigantic and artificial Tree of Life from Disney World. If my digestive system were a tree, it would look like the close-up photo.
From Wikipedia: The Tree of Life is a massive fourteen story (145-foot) tall artificial tree that has been the icon of Disney's Animal Kingdom since it opened on April 22, 1998. Engineered from a refitted oil platform, it is located in the center of the park. Its leaves are made out of Kynar. On the exterior of it are carved images of three hundred twenty-five animals. Inside the Tree of Life is "It's Tough to be a Bug!," a 3-D film from "A Bug's Life." It is similar to the tree of Rafiki from The Lion King, though on a much larger scale. There is a hidden Mickey on this tree.
