On first glance you might be forgiven for thinking this illusion does not appear to be doing very much, but if you stare at the image long enough the birds will start to move. Can you tell which birds are moving and in what direction they are flying ?

This is an afterimage painting by artist Dimitri Parant. If you concentrate 30 seconds on the white dot and then close your eyes for 10 seconds you'll see the face of the Mona Lisa.

Tobias Thierer took this photograph of a house on Baldwin Street in Dunedin, New Zealand. You might be forgiven for thinking that the people who live there would have difficulties getting in and out of their front door without falling over, but is it the house that's slanted, the hill it rests on or the cameraman ?

Here's an illusion that's sure to give you a headache. Try staring at the vertical lines while shaking your head from side to side - you should see something interesting.

Naile 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 ?
