Uncanny Valley

almost, but not quite…

Wikipedia – “The uncanny valley is a hypothesis in the field of aesthetics which holds that when features look and move almost, but not exactly, like natural beings, it causes a response of revulsion among some observers. The “valley” refers to the dip in a graph of the comfort level of beings as subjects move toward a healthy, natural likeness described in a function of a subject’s aesthetic acceptability. Examples can be found in the fields of robotics[1] and 3D computer animation,[2][3] among others.”
