This Demonstration facilitates visual exploration of the sequence ,
,
,
,
, etc. in the complex plane. Change the value of
by moving the locator in the image pane. The first 150 terms of the sequence are then displayed, with line segments joining the successive values. For most values of
in the domain, spiral patterns emerge, suggesting a convergent sequence. For some initial values
, the iterates converge to a stable "orbit," rather than to a single limit point. The controls allow you to explore the space of iterations while creating visually stimulating patterns.
