While probably not a technique I will pursue a great deal further (or maybe I will), I did capture an image of one of the pieces leaning back against a piece of styrofoam while sitting on the edge of a plywood board. It seemed to me an abstraction of a face.
The formality of the composition and the effect of the shadows to create a three dimensional space is interesting to me, as are the combinations of symmetrical balance, unity, and the textures in the three elements. This image has a strange "presence", or being, that I enjoy.
