"Improvisation" - Its Theme and Visualization.....

In visualizing "Improvisation", some thoughts and questions come to mind...  is this a vegetarian soup being proposed? if not, where's the meat? what kind of meat would be used in such a visualization - indeed, what is the purpose of this visualization, this 'nature of improvisation' being visualized?  would roadkill do - if so, what kind? perhaps pigeon, rat, and puppy? a hare? why or why not? [note - could had said armadillo, but size preclude this if seeking life size] if not any of the projected roadkill, what else might do - why or why not?  what differences, if any, would come from the choices in terms of sense of life? in terms of originality? in terms of improvising itself?
