Road Side Treasure

I was driving home today when something on the side of the road had caught my eye. A pile of trash had been set out on the sidewalk in the neighborhood. But it wasn't the piles of trash bags that had taken my fancy, it was the the white plastic corner of an object sticking out from beneath them that had. Pulling over and planing my jog to the pile in between passing cars (as to not be perceived as a crazy) I took a quick look around and slid what I had been looking for from beneath the trash - a used, yet perfectly working, multi-speed fan

I have been thinking up ideas for my haunt that would involve tweaked fan motors, but didn't want to have to buy them. Now I can get to work.

What sorts of things have you found and turned into haunt material?
Any ideas or tips for this motor?
