I'm about to go into production on Big the Musical.  We'll be going with a smaller, stripped-down concept, so I'm trying to figure out how to do the transformation at the end.  We don't have a huge budget, but I thought about the idea of walking through a door or a mirror...I'd rather not do a lot of splashy effects.  The goal is to make it look seemless and simple.  Any thoughts?
