The Fountain was originally intended to be a fireworks pattern reminiscent of a rocket going up and bursting in the sky, but the natural shape of the tree made it look more like water bubbling out of the ground.  A little change in the template made it so that it looked like all the water was bubbling down the tree.  The fountain has a total of 18 steps, each step running for about a quarter second.  When the tree is in automatic cycle mode, the fountain runs 6 times before advancing to the next pattern.
