To zoom in to a given area, drag out a box in applet area and then press the "go" button. You can move the box around once you have dragged it out by placing the mouse within it and holding the mouse button down. Do not press "go" if there is no red box displayed or you will end up zooming to somewhere very boring.

There are two selection boxes one changes the iterations which governs how detailed the image is, the higher this number the slower the rendering speed. The other gives a few colouring algorithm's. Note: Making a selection results in the effect being implemented straight away. Do not press "go".
