IFS (Iterated Function Systems) Fractals are images created by smaller images of themselves. Each different color is an image of the whole image. These fractals are mathematically created in this app. To create specific images, one must crunch some numbers to input input into the app.
The app has a tutorial, the fractal generator, and a selection of fractal images to recreate. The tutorial explains in depth how to get numbers needed for a specific fractal image.
