I always love a challenge and have been thinking about Fractals for a bit and wondered if I could use them in a web page.
Fractals are built using a shape at varying scale many times over. An example of real life usage of Fractals are the aerials used in mobile phones. These aerials are wound inside the mobile phone at a smaller and smaller size and are equivalent to a huge long aerial which would be impractical to attach to a "mobile device".
Here is the product of the project. All the circles are generated from a single text file reading data.
Also note that the webpage uses "vectors" and these can be scaled to any shape.
