This picture has been made by writing original C++ code on a computer. It is less symmetric than it would be otherwise because a 2-vertex directed graph with probabilities has been used to restrict the order in which the various functions are applied (the functions being trigonometric functions composed with low degree polynomials).
The original digital image file size is 12960 x 9720 pixels, however it can be created at much larger file sizes if required. Here it has been resized to 1200 x 900 pixels.
The other view shows a print of the picture, which is of size 48cm x 36cm including the frame.
