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


If you don't believe me, paste the image into an editing application and measure the colours or print it out and cut the squares out with scissors.

Can this be it?

PSP says they are but I don't beeeelieve it. It is probably fooled just as we are.

Don't bother pissing around with PSP, etc. Just make small hole on a piece of paper and look - they are the same.

Are you really an IT contractor traj? Why do something simple like that when you can spend far longer on a computer solution?

Of course I'm a contractor. I've just billed then an extra 60 quid for the paper and the damage caused to my Bic..

I like this one. I like the way it doesn't move.

PRC...Your not supposed to go posting the Alpha Centurai Wormhole Schema to all and sundry.

Now look what you've done.

I have a small horde of Desidodemons running amok in the living room, eating the sofa, carpets and cheese plants.

Thanks a bunch mate.

Anyone have a spare copy of the A-C Return Wormhole they can post, so I can coax the little blighters back to their own dimension please ?

Looks like 1970's vinyl wallpaper. Great stuff.

Someone gave me some textbook of optical illusions as a present a few years ago. It's all in Danish, but shows you how to design them.

Threaded is reminding us how clever he is by being able to read Danish and telling us he has at least one friend.

Be fair, he never actually claimed it was a friend that gave it to him.

Also, he didn't actually claim to be able to read it...

It could be all in pictures...
