Original Wedding Cake Idea

I love cake and I love new ideas that I've never seen before. I was watching the food network yesterday and I saw Krispy Kreme will custom design a wedding cake for you out of doughnuts!
What could be better. It's an idea I'm going to consider, because it is substantially cheaper than a normal wedding cake and it's not something that you see at every other wedding reception. Or may that could be John's Groom's Cake. I can't wait to make those cake tasting appointments. I'm going to make those when the weather gets warm enough to heat the pool water. Because I will need to be exercising those extra calories away!
