Yesterday I watched the DVD of the Jan Svankmajer film FAUST and it gave me an idea to possibly perform a scene from it at out puppet slam. The scene involves a jester who has discovered how to summon devils by repeating enchanted words. I think the words were "feezlekay" to summon the devil, and "fozzlekay" to make him leave. I have reserved a copy Goethe's Faust from the library to research this a little further. I plan to build simple glove puppets, a jester and 1 or 2 devils. I think paper mache heads and hands with cloth torsos would work just fine.
