I think one of the best optical illusion I've ever seen is this one:
The two coloured squares marked A and B are the same colour! Try cutting and pasting them side by side in paint or printing it out and cutting one out and placing it next to the other to see this.
Hi Adam :
Your example is a really good one.
I noticed how computers programs are so helpful for doing those optical illusions.
Do you think the same illusion will be repeated if it is used paint? I mean real paint.
Op Art was an Art movement of the early 60's or late 50's I guess so.
It is amazing how they did those paints without having the technology of today.

Not just with paint, but even with real-world objects. Consider the cafe wall or the barber pole.
Hi Ensign S.:
Your examples are also good. Those are ways are illusions works. I even consider myself an illusion in some kind of sense and you can be my illusion .
Maybe I was not explicit enough in my particular question about Adam's example.
I was intrigued to repeat just that example using real paint , example : oil or acrilic. To see if the same mixed color fits on those two squares. Probabbly yes. But I was intrigued because of the use of the computer so maybe requires a hard study to do the same with mixed paint.
My theory is how the marked squares interact with the colors of the neighbors giving that fantastic illusion.
Oh, I forgot also to tell about the great and now classical optical drawings and Artworks Escher did , without using computers. I think he is ironically more popular now.
Here's a nice one - it makes a black and white image look like it's in colour.
First, move your mouse away from the image, and stare at the dot without moving your eyes for about thirty seconds.
Then move your mouse over the image (keep looking at the dot). You should see a full colour image for a few seconds, even though the image is actually black and white.
I copied the images from this website so I could embed them here.
Is it a trick? From the code, it looks like he's just bouncing between the two images (not any with colored frames in animation or the like.) It works for me if I show each of the two images in separate browser windows and then minimize the colory one.
If it's a mouseover trick, I'm interested to know how he's doing it! Awesome, indeed.
So named as it first came to popular notice with pictures of Margaret Thatcher. It seems that our brains look at eyes and mouths separately. Though we can tell that the whole face is upside down, we can't seem to see that the eyes and mouths are wrong for that face orientation.
I get a bit of an optical illusion with the FSM image posted by DavidMabus0000 in another thread. As I scroll down, the image moves up the screen but appears to get larger as it does so. Or is it just me?
I can see that effect too, Dingfod. I don't see the same thing with avatars and other images on this page - perhaps it's something to do with the bold contrasting lines of the FSM image.
