A method of flow visualization by using photochromic dye is presented.  This concept provides an univasive, visually pleasing way of observing fluid motion of many natural and unnatural phenomena.  Two example uses of photochromic dye flow visualization are presented and observed; thermally driven convection and flow reversibility at low Reynolds numbers.
