I was inspired by memories of an old B&W film Hiroshima Mon Amour (http://en.wikipedia.org/wiki/Hiroshima_mon_amour) where there is a small section where the lovers embrace in what looks like sparkling fallout.
The ones below are my vision, which is not so grim. I imagined skin being dusted with stardust. I created these images using a macro lens. The skin is dusted with flour, water and iridescent sparkles.
