This is a method of rendering which greatly speeds up the calculation rate because the pen is not used during the mapping. It is 100x+ speed(I haven't clocked it but it can render the 100 million points in around a minute on Turbowarp). The calculation speed could be slower if you used coloring but it would likely still be really fast. The fractal featured here is the Clifford attractor.
