The Fibonacci Spiral Model draws a geometric spiral whose growth is regulated by the Fibonacci series. Its growth parallels the rapid growth of the series itself. The golden spiral gets wider (or further from its origin) by a factor for every quarter turn it makes.  To produce a uniform distribution in the plane of the spiral, points are separated by the golden angle.

The Fibonacci Spiral Model was developed using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.   Double clicking the jar file will run the program if Java is installed.  You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.
