If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink.

However if you stare at the black '+' in the centre, the moving dot turns to green.
Now, concentrate on the black ' +' in the centre of the picture.
After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

 

That's a laff ............very good

If you stare at it long enough you can seea boat appear in the background

Good one... both of you.
However, I've been staring at Harry's pic for over 10mins now, and I still don't see a boat.

 

My wife says were just a bunch of smutty gits .

And your point is?..................................

 

Smutty gits?? Dam right we are. Anything less would be unnatural!!

Wait... what were we talking about?? My mind went blank for a second...

You know, If this thread gets an abnormally high number of hits, it's probably just me coming back again and again. I love optical illusions!!
