# Flowsnake fractal

## World's simplest fractal tool

This utility lets you draw the amazingly beautiful flowsnake fractals via a very simple and convenient interface. You can manage the fractal's generation process by changing a variety of settings, such as the number of iterations, color palette, drawing brush's thickness, fractal's direction, image size and its padding. Fun fact – asymptotically, the flowsnake curve fills the entire hexagon-like shape and forms a Gosper island. Fractabulous!

Flowsnake fractal tool
What is a flowsnake fractal?

This online browser-based tool allows you to interactively illustrate flowsnake fractals. The flowsnake fractal creates a snake-like path that never crosses. The path of a flowsnake is constructed from a continuous line that at every couple of steps is always bent by 60 degrees. This fractal is also known as the Gosper curve. It's named after American mathematician and programmer Ralph William Gosper Jr. The famous mathematicians Mandelbrot and Gardner have also called it the Peano-Gosper curve as it has some similarity to the Peano fractal curve. It's also very similar to the Hilbert and Moore fractals as it's space-filling. However, unlike Peano, Hilbert and Moore fractals that fill a rectangle (or square) shaped space, the Peano-Gosper curve fills a space in the shape of a distorted hexagon. This distorted hexagon is called the Gosper island and seven of its copies can be joined together to form another larger copy of the island. Mind blowing and ingenious at the same time, or as we love to say – fractabulous!

Stage-three Flowsnake Fractal

This example displays the third stage of Peano-Gosper fractal. Stage three means that it has been iterated three times. This example uses a square canvas with a size of 900 by 900 pixels and padding of 20 pixels. It draws a white snake line with a thickness of 7 pixels on a pink background.

Gosper Island

In this example, we create a Gosper island. The Gosper island is the final shape of the flowsnake fractal when the iterations count is large. In this case, it took 6 iterations to fully fill the hex-shape space that the flowsnake inherently occupies. Fun fact – Gosper island is a space-filling tile that can cover the entire plane. The colors used for drawing this fractal island are maroon-oak and lemon-chiffon.

Stretched Flowsnake Curve

In this example, we've stretched the flowsnake fractal vertically with a ratio of 1.2. We're using a rectangular canvas with the width equal to 1000 pixels and the height equal to 1200 pixels.
