The people in the boat can't see the boat either

Not nearly as fun as the one in the OP, but fun none-the-less.

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.

Does God have a bugzilla?

lets not gloss over the 'boat' thing quite yet. I still dont see it

Maybe the word boat is a now another word for "woman in a bikini"?

The turning green part is not the illusion. It really does turn green.

No it doesn't.

Yes it does; your monitor just may not be calibrated properly.




Just like the boat in the OP.

Kevy - very cool, reminds me of art school
