This beautiful tree silhouette reminds us of the plains of Africa where the big cats roam.But why does it make us think of cats? Can you see the illusion?
This illusion is an modern take on an old favorite. The two roofs of these high rise blocks in New York City are highlighted in red to make it easier to see. They look to be completely different shapes, but if you take the roof on the left and rotate it 90 degrees clockwise it will fit exactly over the roof on the right. Pretty amazing eh!
Not sure if this illusion works in all browsers or devices but it looks pretty good on our desktop PC. Can you see what is going on here? Try clicking Ctrl A and see if all is revealed. Or try highlighting the picture with your mouse.

We designed this flag using the colors green, black and orange. It doesn't have the same ring as Red, White and Blue so if you long to see the original you are going to have to stare. Just stare at the center of the flag for about thirty seconds (but the longer the better). Then look at something white like the ceiling , a white wall or an A4 sheet of paper.
We have made a foggy city optical illusion for you. The picture below shows the same city covered in fog in daylight and in night-light The illusion is that both sets of buildings are exactly the same color. If you want to check this you could just print out the picture and cut out the two skylines.
At first glance we have two stools that have been manufactured as a conjoined pair, which is a bit unusual in its self. But on closer inspection this has the feel of an impossible triangle about it.
Here we have an optical made up of an outer star and an inner star. The color between the two stars seems to be light green. But this is just illusory, there is no color between the two stars - it is as white as the background, it just looks light green.

This moving graphic is by illustrator Dain Fagerholm, who refers to his work as a Stereographic Drawings. We would call them two parallel still opticals which vary slightly in angle . When you combine the two together they create a 3D image.
Fagerholm uses ink and markers. In this optical the unearthly monsters appear like sketches that have leapt off the page and broken into the third dimension. There’s something creepy yet not all that threatening about the characters. Are they angry or are they screaming - what do you think?
This illusion is one of those that you can never completely understand. If you try and follow the patterns around, your eyes somehow seem to get diverted to a different line as if it is a spiral. When if fact they are all circles. So we have called it Spiricles.
This illusion looks a bit like a child's drawing of a boat out at sea. We have the blue sky and the blue sea with a nice red boat right in the middle. But is this boat moving and if so which way left or right?
