The zip-file below contains three programs: Mandel, Dots and Pythtree.
‘Mandel’ draws the Mandelbrot set, the various Julia sets and a variation on the Mandelbrot, what I have called in the program ‘Mandelbrötchen’.
In Mandelbrot mode, clicking the mouse will zoom in on a particular area. It won't respond to clicking until it has finished drawing, so don't go clicking repeatedly. Pressing any key will take it into Julia mode. Clicking anywhere here will redraw with a different c value (where c is a complex number). In ‘Mandelbrötchen’ mode, clicking will draw a Mandelbrot set with different starting values of z: this is rather a strange picture, and not many programs will produce these.
‘Dots’ shows what happens when you perform the z → z² + c iteration on a complex number. Just move the mouse over the Mandelbrot! |
‘PythTree’ is a geometric fractal. It is made up of lots of squares and
right-angled triangles, which when put together make quite an interesting tree shape.
In the program, the tree is animated by changing the angle on the right-angled
triangle.
