Hmmmm...an argument can be made that when one is working only on technique the subject can be a simple sphere. One could could then render a plain sphere, or with some effort and technical know-how, a decorative texture, or additional supplementary model/mesh embellishments could be added which would break the monotony of spheres alone rendered in a finite number of technical applications of light, position or placed in various environments. Of couse some would argue that the plain old ordinary un-embellished sphere is beautiful simply by design. Others might argue that it is enough to work only with the unembellished sphere....then there will be some clever person who puts two sheres together and says....look...I made Boobs! Maybe the alternative is to recognize the boobologists with the golden boob award....
