This cake has inspired me. Basically something similar to this will be at my wedding (if my husband is at all cool- and if he isn't I may just do it anyway).
Also, I would want this to sit on my bookshelf forever. It is so cool. A really great picture for my wall is a must (if we have to eat it- I really would prefer to keep it forever).
There was also an epic R2D2 cake, a pretty cool Minas Tirith cake, and the cutest Pac-Man cake ever (not that I've ever even played that- it's just so cute) but this won by a long shot. Here's the link to all of them: http://www.buzzfeed.com/gavon/30-nerdy-wedding-cakes
This is the best cake I have ever seen in my life. I LOVE it.
