    Here's another following the catenary principle. Again, I've left the bowl disconnected from the foot to underscore the hanging chain shape. These have been surprisingly popular and one sold before I could photograph it. Lignum Vitae, unfinished (polished wood only).

    The next one I do will be short and wide.

    Take a metal tub and fill it with epoxy(maybe it was plaster of paris) slowly spin it until it almost reaches the edge. leave it spinning until it hardens. The resulting shape is a parabola more than good enough to focus at the quantam photon level.
