Koch Island

/*

This script is a simple example of non-branching Lindemayer systems (l-systems) at work. It is a fractal shape, that depending on the number of iterations, has infinitely scalable detail on its edge. If you choose to use more than 3 iterations it is possible this may take several hours to run.

IMPORTANT: This requires the 'aa_lsystem.mel' script from the script library, as well as the 'aa_turtle.mel'.
