Fractals
A fractal is a picture which is self-similar, which means that if you magnify a part of it, it will the look the same as, or similar to, the whole picture.
Pictures:
Mandelbrot Set: (click a picture for a bigger version)
These are pictures of a fractal called the Mandelbrot set. Each picture is twice the scale of the previous one, so the last one is 4096x zoom. Notice how the last picture contains an image of the whole Mandelbrot set (although somewhat distorted).
Trees: (click a picture for a bigger version)
Each one was drawn by starting with a single "seed" particle in the centre of the screen, then another particle randomly moves around until it hits the seed and sticks on. Another particle is generated; that sticks on to the seed, and it eventually grows into a "tree" shape. Each particle starts at a random point on a circle around the seed, and if a particle goes more than a certain distance from the seed, it's deleted and a new one is started.
Downloads:
Mandelbrot viewer: mandel.zip. Use a zip program to extract this file (into an empty folder preferably). mandel.zip contains mandel.exe, alleg40.dll and readme.txt.
