A photo of artistically painted window blinds was the basis for this Liquib
example. The Mapping feature was enabled with (z-1)/(z*z+i)
chosen as the Complex Variable Function. The Stylus Tool Up and
Down sequon was applied, then an Evert Mutation with the Fractate
and Bifurcate options, a Vivid Rings Tint, and finally the Relief
Tool.
