Looking Into Einstein’s Face: Mind-Bending Illusion!!
This illusion just gives me the creeps. What an amazing example of how powerful some of the hard-wired tendencies of the brain are. No matter how hard you try, Einstein’s face will always appear to be coming out at you.
As Stephen Fry mentions, our vision system is specially trained to pick out human faces. We start doing this at such an early age that our neural circuitry is actually predisposed to do it. You literally can’t overpower your synapses on this one.
My cortex hurts.
