Rayleen explains of her current work "The Images of Star Stuff series are inspired by the physics of the universe. Chemicals and particles collide, they work together to create celestial bodies, or react against each other to separate and disperse. This is universal order. It is found in all interactions, physical, spiritual, interpersonal. It is you. It is me. It is everything".
