OK, so this guy isn't really a giant, if you look carefully you will notice that he is standing on a ledge up above all the people in the background. But it does make you look twice, doesn't it? Image source unknown
These two cars look completely different sizes because your eyes see the 3D perspective you would normally associate with a 2D photograph. But the actual 2D size here is exactly the same. Original image source unknown.

A bit of a reversal on the old perspective illusion for you here. Hopefully this one might fool you.
The Moon Illusion shown here is an interesting one. The two two moons are exactly the same size but somehow the one on the horizon looks a lot bigger. You can see a few more of this type of illusion here - perspective illusions.
We have designed a new perspective type illusion for you today. Here we have a typical skyscraper with two window cleaners cradles hanging from the top. The perspective of the photograph makes it look like the one at the top is much longer than the one at the bottom. But on the two dimensional picture they are actually exactly the same length. If you don't believe us, get your ruler out and measure it yourself. See - I told you. (don't you just hate know it alls)
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.
We have added a couple of flag poles with union jacks to this excellent picture by Mark Hare. Believe it or not the little flagpole in the bottom left hand corner is the same height as the larger looking pole over on the right.
Our latest design is called 'Spaceships'. It shows two space craft fly into a wormhole. The largest one is in front followed by a smaller ship. So where is the illusion? Well it's that actually both ships are exactly the same size.
This is an illusion of the perspective type. On the left hand side we have a graphic representation of the seven tallest buildings in the world. The tallest is the Burj Kahlifa in Dubai shown on the far left. On the right hand side we have another picture of the Burji. The illusion is that the two pictures of the Burj are both the same height. You can get more pics of the tallest building here - The Worlds Tallest Buikdings
