A mirror assembly capable of continuous flexing or undulating is constructed of a flexible sheet material having a reflective surface. Flexing means including opposed roller pairs for engaging the longitudinal edges of the sheet material to impart flexure thereto extends from rotatable chain means disposed along the longitudinal edges of the sheet material. Upon driving the chain means, the flexing means traverses the longitudinal axis of the sheet material causing the sheet material to continuously flex or undulate.
