Hello all! I am helping with tech/stage design for a production of The Snow Queen Musical. I am looking for a few effects to really wow the audience. First thing we are doing is remote controlled EL Wire in the Snow Queen's costume that the actor will trigger to make her dress glow when she kisses Kai to simulate her magic. The place where I am stuck for ideas is on how to show the freezing on the actor playing Kai. I'd like it to be somewhat apparent, some kind of effect that shows him or his costume being frozen. Any ideas?? Thanks!
