We are big fans of Salvador Dali here at optical spy and will eventually produce a Dali Gallery for you. But until then here is one of our favorites. It is called Swans Reflecting Elephants. This painting is from Dalí's Paranoiac-critical period. Painted using oil on canvas, it contains one of Dali's famous double images.
This archway is unfortunately a bit obscured by a tree in the foreground. If you look carefully at the top of the picture it seems that the arch would not actually meet at the top behind the tree. This is, of course, an optical illusion. Click on the picture to see it without the tree.
This our interpretation of the original called 'The Spine Drift Illusion' by A. Kitaoka's
It's hard to believe that the tops of cubes A and B are both the same color. So we have animated cube A to prove it to you. Unfortunately your computer or device will need to be able to run Adobe's Flash to see it. Not all devices do.
Krishna's Butterball is a giant natural rock perched on a hillside in Mamallapuram, India seemingly in defiance of all laws of physics—it's a common sight to see visitors placing hands under the stone posing for pics, which looks as though they are holding it! The rock provides welcome shade if you dare to sit underneath it, and local kids have discovered that the slippery nearby hillside also makes a great natural slide
“On April 23, 1972, Apollo 16 astronauts Charlie Duke and John Young embarked on the third and final EVA of the mission, exploring the Descartes Highlands via Lunar Roving Vehicle. During the EVA, before setting up a Solar Wind Collector, Duke placed a small family photo he had brought along onto the lunar surface and snapped a few photos of it with his Hasselblad film camera.
“This is one of the photos. The family photo, gingerly wrapped in clear plastic and slightly crumpled from being stashed in the pocket of a space suit, was left on the Moon. It presumably still sits there today, just inches away from Charlie’s boot print — which, presumably, is also there.”

In the UK and around the world one of the most popular team sports is cricket. An interesting game where the idea is for the batsman to stop the bowler hitting his wicket with the ball. The wicket is made of three wooden stumps. But our batsman's wicket seems to have an ambiguous amount of stumps
Is it possible to make an alphabet out of just three rotating discs? The three discs above are able to portray complete words just by twisting them in to different positions, it doesn't seem possible does it? Well as ever it's not as obvious as it looks, first you need six discs per letter. Are you starting to get the idea. Here is how we do it.
One thing you have to be very careful of is - when you hold a very heavy rock above your head you are quite likely to fall over backwards. Or is something else going on here? Click on the picture to find out.
The Shroud of Turin is a linen cloth bearing the image of a man who appears to have suffered physical trauma in a manner consistent with crucifixion. It is kept in the royal chapel of the Cathedral of Saint John the Baptist in Turin, northern Italy. The image on the shroud is commonly associated with Jesus Christ, his crucifixion and burial.
To see this illusion you need to stare at the black and white picture on the left for 30 seconds (try not to blink). Then move your gaze to the white background on the right hand side and stare again. Can you see it? You can click on the picture for a larger view if that helps.
The Atomium is an iconic building in Brussels originally constructed for Expo '58, the 1958 Brussels World's Fair. Designed by the engineer André Waterkeyn with interiors by architects André and Jean Polak, it stands 102 m tall.

Just stare at the cross on the girls abdomen
This illusion is one of those 'stare and wait' pictures. In this one a beautiful young lady is posing in her bikini. But the picture is a color negative.
When you stare at the picture for about ten seconds you eyes adjust to this negative image and then the picture changes to black and white but you don't see it as black and white you see it in full color. Amazing!
Here we have two screens one large and one small. But this is optical Spy so something's not right. Could they possibly be the same height? Surely not, the one on right looks much much larger. Well of course it's an optical illusion - the centre of both screens shown with a red line is exactly the same height.
