I'm not quite ready to deck the halls with bats and ghouls, but when I am you can bet I'm making this bat mobile. Bristol board bats are a Halloween staple of mine. I use this Martha Stewart template. I keep them from year to year (some are going on five years old now, so we make a few fresh ones every year) and we stick them to the living room window where they are spookily backlit by the inside lights, and put them on mirrors. I'm feeling this mobile, perhaps embellished with an outline of silver glitter, over the dining room table. We used to have a light there. Now there's a hole. Long story. A bat mobile would be an improvement, albeit a temporary one.
