THIRD.QTM sept 9, 1992 As the parameters in an iterated function system are changed, the resulting attractor changes (continuously). Here is an example of that, based on two non-commuting affine transformations: (T1) x' = (1/3) x + (1/3) y y' = (1/3) y (T2) x' = (1/3) x + e y' = (1/3) x + (1/3) y + f We watch what happens as the point (e,f) moves around a circle. [ref: Suppl. Rend. Circ. Mat. Palermo 28 (1992) p. 350.] The individual frames were computed by "Fractal Attraction" (Academic Press -- I wrote the wrong publisher on the last one), then made into a movie with Apple's QuickTime software. This file is "flattened, data fork only", so it will be possible (Real Soon Now) to view it on platforms other than Mac.
