How many elephants?

Even as someone who appreciates the photo opportunities to be found on a rainy night - shiny pavements, silhouettes and shadows, light trails and so on, this evening was just too wet and windy to tempt me out for long; also being slightly more cautious of not wrecking my new camera within a couple of weeks of getting it may have influenced me too. Thus it was back home for a bit of indoor experimentation. This time I was trying out the effect of a multiple exposure but with only one (long) exposure by turning the room lights out, moving the subject (a blue toy elephant) and turning them on again, counting to four, and repeating the process. Not entirely scientific but quite good fun, if you like that sort of thing. Now I'm wondering what else I can do with the same method...
