Fyre, formerly de Jong Explorer, is a cross-platform tool for producing artwork based on histograms of iterated chaotic functions.

It implements the Peter de Jong map in a fixed function pipeline through either a GTK GUI frontend, or a command line facility for easier rendering of high-resolution, high quality images.

Fyre features a sidebar on the left to which the user can input the required variables and on the right is displayed the result of the equation.

The resulting image is a map of the probability that the point lies within the area represented by each pixel.

Therefore, the longer that the user lets Fyre render for, the larger the probability map becomes and the more accurate the resulting image.
