More than One Cake?

Have you ever thought about having more than one cake at your wedding?  One of the many daily emails that I receive from Martha Stewart had a great idea for multiple 'pop art'-inspired wedding cakes.  I like the thought of serving several desserts, and having more than one cake would certainly help with the problem of deciding what kind of cake to have.  Maybe a variety of three or four is more my speed. I'm not a huge fan of chocolate cake but I think the one below with the cocoa swirl on the top is my favorite.
