Lambda Map
Robert P. Munafo, 2011 Jul 28.
An alternate version of the Mandelbrot set resulting from the use of a different recurrence relation:
Z0 = 0
Zn+1 = C Zn (1-Zn) = CZn - CZn2
or, alternately, the application of a coordinate transform prior to using the normal recurrence relation:
C' = (C-1)2 + 1/4

A lambda version of the Mandelbrot set appeared in Byte magazine 11 months before the better-known Scientific American article:

The images were created by Greg Turk; based on the BYTE article text, these images were probably created on a VAX 11/750 at West Coast University.
