The Fractal Engine
Supports all sets including 'Barnsley' and saves zoomed animations in small or full screen format with its own animation player. Also, you can save palettes and co-ordinates etc. Fractal popcorn, mountains and plasma clouds are new for v2 as are 3D fractal landscapes (created using spherical mapping or landscape rendering), and images may be overlayed on top of each other. Very well documented with plenty of example files.
