I’ve created a variation of Translucence that uses the “Paris Night” image, a view over Paris, at dusk, from the Maine-Montparnasse tower.  See:
https://segueproject.org/themes-translucence-paris/

This “Paris Night” variation highlights Translucence’s opacity options which can be applied to the header, top navigation, content area, sidebars and footer area.  As more people begin to view web sites through HUD browsers, control over the color and opacity of sites will become critical.

I’m merging the ShadowBox theme functions with the Twenty Ten theme functions in order to add the same theme options to Twenty Ten that are included in ShadowBox.  Hope to finish up in the next week or do and publish to wordpress.org.
