That's a nice turn of phrase FW. Makes you wonder if the paintings in the caves of places like Lascaux also 'danced' by firelight (some of those paintings were executed on shallow three dimensional surfaces in order to highlight the animals' contours). And straying off topic, it's not always realised that the highly ornate and gilded frames for European oil paintings were designed to pick up candlelight and firelight and thereby enhance the painting.

There's a line in Beowulf, "In the gloom the gold gathers the light against it." :-)
