POVray is probably great for animating gui elements. there's oc no gui and not a lot of options for doing fancy stuff, like diffuse light. if all you want to do are basic solids and you type, POV's your baby
being text, povray is math friendly - http://www.dimensions-math.org/ (a good 2 hours to blow)
w/o using a modeler/being an intuitive bezier patcher, you may only get as good as me :p
