endlos is a platform-independent, multithreaded fractal generator. It features thread/CPU usage control, unlimited precision, and over 1600 available smooth/random/function coloring/maps. It supports all the image file formats supported by Java.
Performance improvements were made. The demo fractal "Sun" now takes 01:47:55 (10% faster). Pausing calculation (so that CPU usage stops) didn't work.
