What tools are needed to produce fractals?
Let me suggest that you check out some of Bob DeVaney's work
http://math.bu.edu/DYSYS/applets has a list of useful applets; I (and my
students) have particularly enjoyed
http://math.bu.edu/DYSYS/applets/fractalina.html for producing Sierpinski
figures. Depending on how far you want to go, there is a neat exploration of
the "boundary" areas of the Mandelbrot set at
http://math.bu.edu/DYSYS/explorer/page1.html.
In addition, the Shodor applet at
www.shodor.org/master/fractal/software/Snowflake.html allows students to make
snowflake curves, dragon curves, and a variety of other figures.
Finally, the textbook "The Heart of Mathematics" (Burger and Starbird, published
by Key College Press)has some interesting material about fractals; the web site
with applets supporting the text is at http://www.heartofmath.com/activities
check out Barnsley's fern and some of the other activites. By the way, I
recently read this textbook cover to coverit was truly a "good read," and a
great resource for professional development!!!
