Fibonacci Spiral [GO to 'Fibonacci Spirals In Action']

The Fibonacci Spiral is a geometric spiral whose growth is regulated by the Fibonacci Series. Its sudden, almost exponential growth parallels the rapid growth of the series itself.

The spiral itself is a series of connected quarter-circles drawn inside an array of squares with Fibonacci numbers for dimensions. This is illustrated below.


For a demonstration showing how to construct a Fibonacci Spiral from squares, see the In Action page.
