I took a few photos of some of the displays (I refuse to call them "cakes") that I found interesting for whatever reason, so here are a couple that involve royal icing.
I just liked this one because it's a good example of the fact that you don't have to have a white wedding cake. Also, the piping that she used on this is a little more modern than brush embroidery, which would typically be what you'd see if someone did this kind of white-on-black design.
The organizers had also been promoting the idea of having some traditional-style techniques on display, so there were a bunch of extension work designs, Nirvana-style, etc etc royal icing cakes this year. Those are impressive just for the sheer amount of work that has to go into them, but style-wise they do nothing for me. My husband summed it up by saying "Miss Havisham's cake" when he saw one of them. I can appreciate the technical side of it, but I don't want to look at them for too long.
