Animating using rotating material definitions

Here is a spherical icosahedron from renderviewport mode. I believe it could be animated by dynamically changing the material rotation parameter between successive view saves. Is there a way to treat material rotation as a variable? I have found in the XML material definition the following line.
“rdk-texture-rotation type=“vector3d”>0,0,90</rdk-texture-rotation”

@andy can you help here or point toward any scripting samples using the RDK that may provide a solution? It might also be possible to animate mapping values via Bongo 2 but I’m unsure.
