WOW!!!! that is amazingly cool! But i gotta wonder, what do you do with that baby when it's not in use? do you have a warehouse to store your creations or what? that's not "toss-it-in-the-attic" sort of decoration!
i really really love the steam rising from teh cracks and then the lights and rattling before the big pop-up. That is top notch in my book.
