Cupcake Cakes

Everyone loves cupcakes. One way to use cupcakes is to put them together to form what looks like a sheet cake. Now, in my opinion, these are probably best for more informal get togethers, like birthday parties, or whimsical, themed weddings as opposed to a formal, traditional wedding. Here are some cool cupcake cakes that people have created:
