While not quite an optical illusion this image does help to represent the paradox of duality. One of these glasses is half empty and one of them is half full, but which is which ? Is there even an answer or can both be one or the other ?

Rachel Howell sent this impressive afterimage of a butterfly in to us via email, to see the effect try staring at the white cross in the center for 35 seconds and then looking away at a blank surface.

This is an alternative version of an impossible object made out of lego, the straight beam across the top appears to connect to the front and back columns without bending even though they are some distance apart. The lego man looks suitably confused - i don't blame him.

This picture shows two spheres in a brick cul-de-sac, but how large is the sphere in the foreground compared to the sphere in the background ? Another example of the Ebbinghaus illusion these two spheres are actually exactly the same size, the sphere in the background only looks larger because of the perspective in the picture - an observer expects the sphere in the background to be bigger.

The Simpsons have done a lot of unusual things over the years during the famous introduction sequence in which Homer and family rush in to their living room and sit down on the couch in front of the television. In series 6 one episode paid tribute to M. C. Escher's famous "relativity" lithograph, the result is an alternative view of the Simpsons sitting in their living room.
