I can't be bothered to carry on now.

Ooopps, forgot one. If you look closely, they've managed to make the Mona Lisa's face look like Rowan Atkinson:

At first I did not get Mathlida's one but after a few tries I finally got it. For me it also changed green.

I've always loved the scintillating grid (as in the link provided by Huskey).

But here are a couple others:





Are these circles concentric?

Are you seeing wave motion?

My eyes hurt!!!

However I did beat the face picture

This is the best thread ever!!! I will post some illusions after I find them again on Google.

Does it count if I think sight in general is an optical illusion?

I've always liked the Ames's room illusion.



The following is also very good. I mean, despite you knowing they're the same size, it's so hard to perceive it that way unless you try. Just goes to show you how easy it would be for magicians and others to trick us.

Yea, it's amazing.

I did one thing - I put it into gimp and drew a white outline around the B sqare. After that I saw them as the same colour. But after pressing Ctrl-Z (for undo), when the outline suddenly dissapears, you get that short moment of confusion. You feel compelled to take a second look, because something is suddenly wrong with what you see. There is this short moment of "reevaluation". And then on second look, the colours are different again.

Interestingly, erasing the green cylinder doesn't change anything (for me).

Really neat.

I tried this. Really neat!

I suppose I better post it before someone else does

It took a LOT of staring but i can finnaly see the boat.

I thought the gorilla was supposed to mislead me from what was really going on! I thought something was changing in the scene, like a wall changing colour or something and that it would be hard to notice because of the gorilla and the general chaos!

I've always liked the simple 'ol blind spot related illusions

Ummm... i don't get it. What were we supposed to be looking for ?

If you look at one of the points (I don't know which of them, since I haven't tried) the other one will dissapear.

I've found my blind spots.

Here is a page with 50 optical illusions.

Unfortunately it is in Romanian, so you won't understand the explanations. I guess you know that if you click on the images you will see them bigger.

Close your right eye and look at the right spot or close your left eye and look at the left spot. You may have to move a bit relative to the screen, but the other spot should completely disappear. It happens because the optic nerves pass through the retina leaving a non-photo sensitive area (the blind spot). The brain will just fill in the spot with data from the surrounding area, so it will look white.

Also be careful that if you move your eye the dot will appear again. You should be about 30 cm from the screen I think.

I always wanted a moveing desktop now I have one ..... kinda.

Here's a little trick deriving itself from colour theory. Detailed explanation of how colour theory works here.


Instructions:

Choose a heart below. Stare at it for a good 30-45seconds. Really stare at it, let the colour soak your retina. Once you've done that, look to the blank side on the right and then tell me what you can see......
