I would like to have a big room just for my playmobil and Chris's, with three walls lined with tables. I would want to set up every bit of my entire zoo permanently, plus room for Chris to set up his police and fire departments. I'd also like a table for working on other projects, customizing, setting up smaller temporary projects, or shooting photo stories. I would want good lighting for taking pictures, and a variety of backdrops for the photo story area (I don't care about having backdrops behind the zoo dio, just light-colored neutral walls). I'd want the other wall to have some shelves where I can display ships, buildings, vehicles, and such, and maybe a high shelf all the way around the room for the same. Plus of course a closet for storing whatever isn't displayed. And last but not least, a really good ionizer to keep dust off the displays!
