The squares marked A and B are the same shade of gray.

Really.

If you don't believe me, use a color picker and compare the two.

Or visit the link for proof, as well as other cool optical illusions.

Well, if it isn't brand new, you'll probably get a stupid comment from someone.

Who are we calling 'stupid'?...

I know it's old, but I ran across it when organizing my favorites, and I knew there must be a lot of people who haven't seen it.

I posted it in another forum, and some people are hard to convince that it's true.

The reason I said it was 'old'...the exact same image was posted on this exact same forum years ago....[one or two].

I didn't say a stupid comment from "someone stupid", just stupid comment.

Lol @ Jafo & Tarkus.

These are all so easily explained. The only one that actually tricks me is the checkerboard one.

Kind of gives new meaning to the phrase, "I'll believe it when I see it."
