Fractals in Nature

The computer-generated landscapes and clouds you see in Pixar (and other) films are fractals. Now that you've made some fractal structures yourself, check out those found in nature.

  1. Search for images of fractals in nature.
 
  1. In nature, gravity affects how plants grow. Here is an example of the tree fractal that uses a gravity block to weigh down the branches roughly the way gravity would. This tree's branching structure looks like tree with trunk bending to the right by 5 degrees at each place where branches emerge. The image below shows what happens when we add gravity. Experiment with this idea or work on whatever alternative you find interesting and beautiful.
