Hello Everyone! let me first say I LOVE THIS WEBSITE and 2ndly THANK YOU ahead of time for taking the time to read/respond.
Here's my issue. I love to make cakes that are interactive in some way. I've made volcanos explode, spooky cemetary wells bubble over and creepy cabins emmit fog (all done with dry ice). Now I'm about to do another cake for this school and the theme is "fanasty escape 2008". I've decided to make a cake similar to one I found here (I'll be using all fondant/sugarpast and a little different creatures)

but am now trying to find a way to make it do something. I was thinking maybe blinking lights in the windows (the judging will be in the daylight so I'm not so sure they'll even be visible). Any other ideas? I realize this is a bit more difficult since its a book... but there must be SOMETHING i can do to personlize it! any info will be helpful! thank you again!

if you do a castle scene like the picture, i think the dry ice would work if you wouldn't mind using it again, like around a mout or out of a dragon's nostrils? not sure how you would do this but i'm sure you have some idea already

i think the above comment is a good one, not sure what theme you're going with on the book, but if you included a dragon, smoke coming out of his nostrils would be awesome.

humm... now to work out the logistics...
any other ideas?
