Love a good optical illusion?So do we - and so do rats, it turns out.The Asahi illusion is a particularly baffling one that tricks our perception of light.Looking a little like a flower, it features petal-like shapes around a white centre.The petals are black on the outer edges but transition to yellow as they taper, creating an effect which makes the white centre look brighter than it is.
