My permanent wargaming room is next to the entrance hallway of our house, and has a window such that visitors waiting at the front door can easily take a peek in. Once they enter, and unless the door is closed, they usually immediately notice the toy room, as it is called by the other residents of the house.
Hence, I always try to have a nice display of figures set up, almost as if a game could get started any minute. This makes it easier to talk about the hobby, as otherwise stuff needs to be taken out the drawers etc.
So, currently, I made a setup featuring part of my WW1 collection. Also, somewhat appropriate, with the invasion of Belgium being 100 years ago these days. Enjoy.
