Later on, the same recursive principles of fractal imaging have been applied to music to create what has been termed fractal music. After a first phase, when the goal was to produce pure self-similar images of mathematical objects using the best possible colors and some other visual effects, now the tendency is to use fractal programs to create abstract images whether they clearly show fractal structures or not. Other artists combine fractal motifs with photographic pictures or with other images created with advanced graphics programs. But consider that keeping evident the fractal structures in the image and limiting the graphic effects may be an interesting challenge. True color programs that have superseded programs limited to 256 colors should be recommended, but beautiful images can always be obtained with the old programs.
Great artists can do great artworks with limited tools.
Quaternions produce very beautiful 3D images, but tend to be closely related, almost look-alike, maybe because only a few artists have worked in this field. There are some very good programs to create such images, and vocations may be encouraged. There are some very good free tools. Flame fractals are a variety of strange attractors. They have been used by some artists to create original images.
