Here are my entries. The wife, kids and I just put up ours this afternoon. Its a mixture of Department 56, stuff purchased off the shelf from the home improvement stores and drug stores, and a couple of my kids Skylanders video game figures that looked scary enough. The portals (what the Skylander characters are standing on) light up too which adds to the effect.
I no longer have a Halloween train (maybe get another one next year) so we have the Halloween Pumpkin Heads rolling the Handcar around the village on an Atlas O Figure 8 track setup.
I need to get a better camera so that I can get magazine quality night shots.
