This one began as a parameter file submitted to the Ultra Fractal Mail List by Mikko Vainiala in March 2000, with a request for ideas on how to
improve the image. Janet Preslar turned it into a game whereby list members followed a specific set of instructions until finished.
Example:
Step 1: Rotate Layer 1 *only* 90 degrees clockwise.
Step 2: Delete Layer 2., and so on...
These steps were sufficiently open to individual interpretation so that everyone's final results were radically different.
With Mikko's generous consent, this is the image I obtained.
