Temple of many columnsCategory: Impossible Objects | Added: May 28, 2011 |
55 commentsNaile sent us this drawing of a rather unusual temple, while at a glance it may seem that there\'s nothing particularly unusual about it if you look closer you will find that the number of columns are somewhat confusing to determine. How many can you count in the picture ?

Glass half empty or half full ?Category: Double Meanings | Added: May 13, 2011 |
0 commentsWhile 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 ?

11 commentsRachel 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.

Lego impossible objectCategory: Impossible Objects | Added: April 11, 2011 |
7 commentsThis 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.

Sphere SizesCategory: Size and Distance | Added: April 9, 2011 |
7 commentsThis 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.
