Some colleagues and I have just published a paper in the British Journal of Psychology on the duck-rabbit illusion (the paper was published with Caroline Watt, Ken Gilhooly and George Georgiou and the abstract is here). We basically found that the easier you find it to flip between the two interpretations of the image, the more creative you are. So, in honour of this great occasion, I give you not one, not two, but eleven duck-rabbit images….
