6. First Year Seminar Fractals: The Geometry of Nature

7. Examples of fractals

9. Natural fractals

10. Natural fractals??

11. Iteration Fractals are created by iterative procedures, often many thousands of iterations. A computer helps! The chaos game http://math.bu.edu/DYSYS/ http://www.shodor.org/MASTER/frac tal/software/http://www.shodor.org/MASTER/frac tal/software/

12. Fractal forgeries FDesign software FRACTAL FORGERY PROJECT: Try making an IFS image of a picture of a natural object of your own choosing. Leaves, flowers, broccoli and cauliflower all work well. You can construct the blueprint either by hand (make a sketch of the objects edge and then cut smaller copies, arranging them to mostly cove the image), or using a computer program. Use FDesign or Frame’s Random IFS to generate your final image. Record the transformations used.
