Castle Cake Mold

This would definitely have been my dream cake when I was a little kid. I can't say that I could bring myself to buy too many molds since I don't make enough cakes (maybe one or two per year) but this one is very cool and I kind of want it...badly. I think I mostly want to decorate it.
On the site they say that they've also successfully used it as a chocolate mold and they were also able to make a castle made of ice from it.
