package ifs-fractals

Draws fractals defined by iterated function systems (IFS) in an OCaml Graphics window, using the chaos game. Sixteen fractals are predefined (the Barnsley fern, the Sierpinski triangle, a dragon curve, a maple leaf, a sunflower, Queen Anne's lace, ...), available both from the ifs-fractals command-line tool and as a library for the toplevel. Defining a new fractal is a small record: a handful of affine transforms with their weights and a viewport.
