If you place two mirrors beside one another you can get several reflections.
In the following video, there is a piece of paper in front of two mirrors. There are three reflections when the mirror is still. In two of the reflections the letters are back-to-front but in the other one the letters are facing the right way.
When one of the mirrors is moved, then you can get different numbers of reflections. Again you may notice that every second image the letters are the right way round.
