Animator vs. Animation... characters creating/destroying their surroundings

I have to admit that I was pretty entertained by animator vs. animation. I don’t think that I really need to explain to anyone what was going on, it was pretty simple: animator creates stick-figure, and then tries to kill it. What made A vs. A different and entertaining was that it broadened the dimensions of the story. Instead of the discourse and story space being restricted to the simple plane white canvas of the processing screen, the story was expanded to include the tool bar and the boarders. Every icon and button was in play. For some reason, A vs. A reminded me of the movie Who Framed Roger Rabbit. I know, sounds dumb, but there are scenes in that movie in which the characters simple draw objects and they appear, much like A vs. A when the stick-figure (or perhaps the protagonist) draws lines and shields, only to have them suddenly part of the story, in the form of protection and weapons. The same idea can also be said for Krazy Kat. There are frames in the strip in which a character would draw something (or erase something) and it would affect the story. For example, Officer Pup drawing Ignatz in jail, or Ignatz erasing a brick in mid-flight. I’m not really sure what this story telling effect is called-when I character interacts with the actually physical setting of a story, manipulating it in order to advance the narration-but I enjoy it and like the added dimension that it brings to the form of narrative. It seems to break from the conventional story telling forms of the characters. I guess, since I don’t know what to call this interaction, where characters can create and destroy the setting around them, maybe someone can help me out with an actual literary term?
