Pierre Javelle and Akiko Ido have merged miniature people and (sometimes) animals with food to create interesting scenes. This isn't necessarily anything new, but they were quite inventive with their ideas and had great execution. Check out their website (click here). The project is called Minimiam.
The truth is, it doesn't matter what you photograph. The subject makes no difference. What matters is photographic vision and creativity. Pierre and Akiko certainly possess both, and it shows in their images.
