A cake is a cake is a cake, right? That's only true until creative bakers start adding things that definitely aren't cake -- or even food -- to their creations. From cakes that conceal live doves to ones built into television sets, these projects require talent, organization and the ability to wear lots of different hats.
It's not just that you need to combine baking with construction, though. You'll need to have a good sense of how all the elements of your cake and its presentation are going to go together. And you'll also need to plan ahead in case anything goes wrong. There's a reason for that old saying warning directors not to work with children or animals -- they're a little unpredictable.
