Simple extension to render IFS fractals from a base image, by repeatedly duplicating and transforming selected objects. Transformations are specified as matrices, and should be contractive (i.e., shinking). This can potentially make a large number of objects, but for a small number of iterations and transformations the results should be reasonable.
Based on openclipart work, spiced up in gimp. Original source: https://openclipart.org/detail/241835/arrows-ammonite-4
