ACTUALLY, I think this could be pulled off if we used animated GIFs as characters, EXCEPT that this method would only make the characters move around in a predetermined way (i.e. not really an animated strip).
I think it might be a bit hard to make them completely animated. MAYBE if you took several strips and load through them really fast, kind of as if you were at a page that redirects you to another page which redirects you to yet another page (although that method would only work as well as your connection).
You could also use Java to program something like that in. It wouldn't bear much similarity to the stripcreator engine though.
