There are only 26 letters in the English alphabet yet they can be rearranged and combined to express anything imaginable. There are probably thousands of different characters, poses, light sets, and textures, available for Poser that can all be varied even further and then combined to express anything imaginable. Add to that the old saying that "a picture is worth a thousand words". Combining all of these things is an Art, how can you doubt that? Especially after looking at the galleries?
