The bottom of the work area shows Initial, Now, and Next.
Initial is the original shape from which a fractal will be created.
Now and
Next describe the process that will be used to create the fractal — any element that looks like Now at the current stage will be transformed to Next in the following stage.
There are four options for the shape. They are the Koch Snowflake, a fractal tree, a reduced square, and the Sierpinski triangle.
The New button resets the current fractal to Stage 0, where it looks like the Initial state shown in the bottom left. The +/– buttons can be used to step through the fractal, stage by stage. The Play button runs the entire animation through from the current stage to the last.
Note: Each fractal will be animated for only the first several stages, due to computer limitations. However, statistics about stages beyond those shown graphically will appear in the table of values. The orange rows represent those stages for which the the image can be displayed; the blue rows represent those stages for which there are no images.
