The photo in this thread features the same broken glass and two shards shown in the first thread. I'll only mention for now that Nandakumar gave me the idea of making a photo of the glass that perhaps makes the viewer feel endangered by the sharp point.
I'm very interested in learning the story and mood you feel are being conveyed.

Setup
The setup is exactly as in the other photo except no flag was needed. The tabletop is clear glass and the background is textured blue art paper. A small continuous-light lamp lights the background from below. The liquid is about two-thirds water and one-third glycerine.
