In the gallery I sometimes see a single note by the artist saying "UF3" Maybe I'm wrong but as in the case of fractalexpo there seems no way just one program was employed. Mind you I find it commendable whether one can use 100 programs or just one to produce artistic fascination. I have gotten similar results to the free form fractals by using the displacement function in photoshop to create the dynamic free form shapes. What I would like to know is how some of those textures/tiles/materials are applied.
