Fractal eXtreme is almost fully functional program in demo mode. However, it has a limited zoom range (still greater than most fractal programs) and displays a reminder screen each time you run it. If you wish to continue using Fractal eXtreme, and if you want it to be fully enabled again, you must then purchase it. Fractal eXtreme can be purchased for $34.95 over the Internet, modem, phone, or fax, and will be instantly unlocked as soon as you purchase it.
