My "other" hobby is 1/12th scale (one inch to the foot) miniatures. The Diagon Alley scene was created by yours truly. Dobby and the animals were created by various miniature artisans.
This is very clever! My husband builds 1/48 and 1/72 scale model planes so I know how much work goes into these miniature scenes. He's currently collecting bits for a WW2 landing field diorama he wants to put together.
