• Platform independent: runs on any Java virtual machine (1.5 or later; 1.6 up to twice as fast!)
• Multithreaded: uses any amount of threads for faster calculation on computers with multiple cores/CPUs.
• Unlimited precision: use any amount of decimal digits for endless zooms (with fast modes for 32/64 bit precisions).
• Smooth coloring: days of boring low color stripes are gone.
• Random coloring: see color maps that nobody else has seen before!
• Color maps: support of color maps (*.map) - separate package with over 1600 color maps available.
• Draw modes: choose between draw modes to see pixel, line, block or only full image result.
• Fast zooming: get an instant preview of the location you're zooming into.
• Multi Fractals: calculate as many fractals as you like at the same time (incl. pausing).
• XML Fractal Settings: save & load your fractal settings.
• Automatic saving of last setting: continue with your last fractal setting.
• Image formats: any file format supported by the Java virtual machine (PNG, JPG, BMP, etc.).
• Open Source: GNU General Public License (GPL).

endlos is german and means endless, infinite, ad infinitum. But not only fractals are endless, the platform independency enables endlos to run on an endless amount of operating systems (having a JVM); you can use virtually endless threads making endlos faster the more cores your CPU has; the precision mode 'unlimited' can virtually use endless decimal places; the permutations of random colors are higher than your eyes visual spectrum; the number of parallel fractals are only restricted by the computer's RAM and your screen's dimension; Open Source has the potential to live forever.
