Title
The Paramathematical Gallery
Description
Ultrafractal is designed to plot fractals like the Mandelbrot Set or Julia sets, but it's incredible possibilities allow to explore a wide area of geometry (Tilings, Polyhedrons,...), as well as many types of fractals (Hilbert and von Koch curves, Brownian clouds, some iterated function systems).
Ultrafractal use layers similar to those in Photoshop or Paint Shop Pro. The color of a given pixel on a layer is determined only by a succession of computation performed on the pixel coordinates. This could seems rather restrictive at first sight, but, thanks to the layer feature, it's possible to make "worked" images and even realistic scenes (see the space scene gallery). Moreover it allows to draw quickly patterns that would be either impossible or very long to produce by hand or with a standard graphic program.
Why Paramathematical ? Well, because some of them can have a more or less obvious mathematical interpretation, some not, even if they are all strictly algorithmic.
