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.

Simpsons EscherCategory: Impossible Objects | Added: April 8, 2011 |
4 commentsThe 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.

Sideways car illusionCategory: Double Meanings | Added: April 7, 2011 |
10 commentsThis well circulated picture of a vintage car might seem like nothing unusual at a glance but look a bit closer and you'll notice that the direction its facing isn't quite as obvious as it first appears. The addition of the spare wheel works well to make the image even more confusing - is the car facing towards you or away from you ?
