Flaming Pear (do a google search) has many filters (several free) that modify the structure/coloring etc. of your basic fractal images. They have their own tutorials with the product. Although a few fractal programs have their own filters and such to manipulate the image, sometimes it can be profitable (artistically speaking) to employ an off-base filter. The results should still be considered 'fractal', as the image is fractally derived. The best tutorials are the ones you discover yourself. ;) Stan
