These images are part of a series of photos created for an advertisement for medication to help people suffering from Alzheimers. Alzheimers is a condition where recent memories are stripped away leaving the sufferer left with memories of their youth. So we the mirror used as a way of showing how the person sees themselves, in contrast to how they appear to those around them.
You can find lots of artists and photographers using image manipulation software like photoshop to play with reflections in mirrors, but this is the most striking and effective I have seen.
You could have a go yourself using two photographs of reflections in a mirror using photoshop, the hard edges of the mirror makes fitting together the two different images fairly easy. You could create an image that looks at differences between how we see ourselves and how we are seen by others
