I got this idea from ganda, who posted an optical illusion.
So I thought I’d start a thread where all of us could post our favourite optical illusions.
I’ll start:
This one is my favourite. Actually, both the ‘blue’ and the ‘green’ field is the very same color. If you don’t believe me, save it and open it in paint.
This one is really good because it shows how we interpret what we see. If we didn’t have processes that optical illusions can exploit, vision would be useless, we’d only see “bitmaps” and wouldn’t be able to tell at all what objects are causing that light flashes in our eyes:
vision is a matter of deriving a [b]probable[/b] interpretation for incomplete data.

Zooming a lot (~50x) also works since a bigger area is less likely to have it’s colour mistaken beacase of the surrounding colours.
