When we analyze in what looks like a fern, the coast and a snowflake see the concept of self-similarity appears recurrently, giving rise to geometric shapes based on the concepts of recursion.
Fractals are geometric figures, like triangles and rectangles, but with special properties which distinguish them from these. First, are very complex, any size. Tienen autosimilitud, namely, which can be divided into parts that are small copies of all. Unlike other geometric figures its dimension is a fraction.
We can also make these figures to three-dimensional spaces through geometric transformations, as the following example built with Blender to be used as desktop background.
