Take an image of whatever subject you wish, and make it look as though it is starting to disintegrate. You can go with more of a sand/dust effect, or perhaps a paint splattering approach. There are endless ways to achieve this effect. Whatever you choose is fine as long as your subject is not a whole piece, but partially solid and partially being dispersed. Here is a tutorial for some inspiration if you don't know where to start.
