Does anyone know some really good programs for creating images on the computer? I'm really looking for a program to make surreal abstract images or realistic images.
Terragen (photorealistic landscapes/waterscapes/and now spacescapes, free), Bryce (not free, basic 3d modeling), Blender, free, 3d modeling, similar to rhinocerous. Daz Studio for photorealisticish people and animals. Apophysis for abstract fractal flames (very popular in the abstract gallery). It's free.
You can also read the Frequently Used Software list (i think it may be found in the FAQs).
