Disneyland and Walt Disney World each host a unique ghostly horse outside their Haunted Mansions. In both locations, the spirit beast stands harnessed to a carriage hearse. Disneyland's hearse is painted white to match the New Orleans Square mansion's exterior, while WDW's hearse goes for the traditional Gothic black.
There's something oddly comforting about the ghost horses, and they've helped many small children overcome their fear of entering the ride. (How many of you have encouraged your children to "feed" an imaginary apple to the invisible creature?)
Anyway you look at it, the "hovering" harness gear is just plain awesome. This is low-tech, well-crafted brilliance at its finest.
