Mandelbrot Fractal is a good-looking and easy-to-use JavaScript-based fractal generator.

There's no installation, as the package is hosted within a web page. All you have to do is unzip the download and open index.html in your default browser.

Clicking "Launch Fractal" briefly displays a menu of options, before generating the usual initial Mandelbrot view.

Click an area of interest and Mandelbrot Fractal zooms in, redrawing the fractal at that point.

Right-click the window for an option to save the current view as an image.

If you've got lost, or find the area's drained of colour (which can happen if you zoom in too far), other hotkeys will reset your starting view or close the program entirely.
