There is a proverbial anthropological anecdote concerning the projection of a film by some anthropologists for a - as was once called - primitive tribe. They asked the tribe what caught their attention in the film; the answer they received was "the play of light and shadow". This is I think the underlying premise of this short, but I suspect with a slight twist: what would these solar flutters mean to "us", civilized, image-ridden people?
I can only answer in an experimental, impressionistic manner: think of the Tassili-N-Ajer rock images, think the quality of pre-Colombian gold; think of Max Ernst's weird Euclides, and Klee's Black Prince, imagine eyelids mesmerized by this self-reflexive, generous, elusive like figures evaporating on the wet sand film, along with its tribal, ethnic, social delineations (not in celebration of some deeper, organic unity as the trend goes, but) after something enigmatic. Not as solar as the title suggests, a bit closer to the heavy odor and the colors of the night-flower.
