I noticed that some of the images that Rossier created were stereographs.  These are a set of two photos taken from slightly different points of view.  With a stereograph, instead of looking at one image with both eyes, each eye gets a separate point of view and the illusion of depth and fullness is created.  As with stereo audio, stereo photographs take advantage of a fuller range of perception to create a richer experience.  As with any stereo form, our awareness, though we are stimulated by multiple sources, is of one impression.  There is a synergy though.  Something wonderful and complex comes from the combination of two simpler forms.  In the song I draw a parallel to the intricate and fascinating result that evolves from the combination of two humans in love.
