Henri de Toulouse-Lautrec was a French painter, printmaker, draughtsman and illustrator whose immersion in the colourful and theatrical life of Paris in the late 1800s yielded a collection of exciting, elegant and provocative images of the modern and sometimes decadent life of those times. He painted many posters for the local dance halls. 

This poster shows four dancers doing the famous 'can-can'. But hidden in the image are four onlookers, can can you spot them?

Thanks to Vidram for sending us this picture of a couple of guys scaffolding. It's not until you look a little closer that it becomes apparent that all is not what it seems. As we have no way of verifying this picture we have to assume a bit of photoshopping has been going on, but it really is a great illusion. If any of you have any good opticals you think we may like please upload them over at our contact page.

Here we have an illusion with a chair or two (depending whether your device can see flash animations). No matter if you can't they are both showing the same illusion. The idea here is try and determine which way the chair is facing, either towards you or away from you. The confusion seems to bee that the legs do not change sizes.

This video has been carefully designed to create a strong natural hallucination.
Use full screen for best results.

The green gentleman on the left has a unique skill. He can change the color of flowers. In this case it's the white rose on the right.
To see this effect you will need to fairly close to the screen and stare at the green man for at least 30 seconds (just count slowly in your head) without looking away. Then look at the flower on the right.

If like us you are a fan of Liu Bolin - the famous Chinese artist. You will enjoy this video of how he does what he does. It's fascinating.

This magnifier looks like it helps you read the text but actually it does nothing at all.

These straws may look like they are bending in the middle but we can assure you that they are perfectly straight.

Here are a couple of pictures of cows we found. Hope you can see the illusions.

It's amazing what you see when someone removes the pillars from an old bandstand!

This illusion is a fairly simple one. We have a nice picture of a room shown behind a perfectly symmetrical grid. But the grid looks somehow distorted on the left hand side.
