From the developer:
IFSLab is a revolutionary new way of creatively designing beautiful IFS (iterated function system) fractals.
Rather than having to deal with complicated math, you just define a simple master shape, clone it a few times, resize/remove/reposition the clones and watch in realtime how your IFS fractal develops. All the examples on these pages were created with just a few mouse clicks. It‘s even possible to create movies of morphing IFS fractals.
