Two illustrations for this weeks New Scientist. A suitably creepy halloweenesque piece on research into the eerie visions that can occur when staring into a mirror.
'So professor, we just popped round to see how your research was going? what have you been up to over the last few months? you've been what? you had some people over to stare in a mirror until they saw scary faces? I see. Why has all of your litmus paper got smiley faces on?'
I am being silly! The experiments in fact have some fascinating results confirming the perception of faces (even our own) is not a stable thing shedding light on the volatile process of self identity and even having use in the treatment of post traumatic stress and schizophrenia.
