Imaginary Castles

I'm reading The View from the Cheap Seats by Neil Gaiman. He says, that we have an obligation to daydream. He says: „This room and the things in it, and all the other things in this building, in this city, exist because, over and over and over, people imagined things. They daydreamed, they pondered, they made things that didn’t quite work, they described things that didn’t yet exist to people who laughed at them“. I read it and thought that this is beautiful. And when I closed the book and want to make this picture.
