(No picture I'm afraid: you had to be there...)
I purchased a copy of the graphics program 'Painter', and discovered therein a free sample of a bizzare material which appeared to be a thin, flexible sheet of glass. It was about 6 X 5cm, about a millimeter thin, and as flexible as a similar sized sheet of latex rubber would be. However, it made a clink like a wine glass on contact with a hard surface. On close examination it appeared to be filled with tiny glass spheres or bubbles of some kind. It had a roughness to its surface like a very fine grinding wheel which could be detected by touching it to one's tongue.
It was explained to me that it was liquid, like normal glass, only more so.
