Straight out of the tale of Hansel and Gretel, it’s the world’s largest gingerbread house.
What does this have to do with writing?
Well, for one thing, it’s proof that the real world has a lot of strange stuff in it all by itself, without writers necessarily having to make strange stuff up. (Not that there’s anything wrong with making up strange stuff for the fun of it, if that’s what you like to do.)
And for another thing, it’s a salutary reminder, for those of us who write science fiction and fantasy, that we work in genres where things that in the world of consensus reality are only imaginary concepts, can and do achieve solid three-dimensional existence. Our gingerbread house isn’t just a daydream or a metaphor any longer — it’s right there in front of us, and the door is open.
