The Koch snowflake is a fractal curve that arises from recursively dividing a line segment in three sections and replacing the middle section with two line segments that forms a triangle. It`s a really famous fractal and one that`s really easy to draw.
One cool property of this fractal is that if you switch randomly the direction of the top of the middle section triangle you get a line that resembles a coast.
I`ve written an interactive version of the koch snowflake, including the option to randomly change the triangle direction and a slider to increase/decrease the middle section size.
