As with porting, when refactoring, the changes need testing. Sometimes the test cases generate interesting pictures. Sometimes they motivate the artistic side and the test case becomes a jumping off point for new creations. I like to explore the inspiration when it happens. But the program, being in the middle of an overhaul, is in a less stable state than usual.

Here the goal is to use the rugged terrain algorithm from early posts to add texture to a simple fractal. The previous picture looks like painting on a coarse canvas, or perhaps a needle point. Today’s picture is the same design, but with the texture dialed back some.
