Fibonancci Spiral

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 of φ 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 by Wolfgang Christian using the Easy Java Simulations (EJS) version 4.3.7 authoring and modeling tool.
You can examine and modify a compiled EJSS. You must, of course, have EJS installed on your computer. Information about Ejs is available at: http://www.um.es/fem/Ejs and in the OSP comPADRE collection http://www.compadre.org/OSP .
