I built this for work, to sit next to my monitors. It's a cut-away view of a fantasy tower. I was caught between wanting to do a diorama or to just leave the floors as shelves to display random miniatures. In the end, I opted for both! The basement has spiders pouring forth from a mass of webs and the top floor has a necromanceress working some magic over a crystal ball. They're permanently glued in place. But the middle two floors are empty for other miniatures.
