Observe my avatar , is she twirling to the left or to the right ?

If you liked the one above you'll love these. The first as the one above
illustrates the left right bias present with our bicameral brain.
The second below shows even when both are in agreement it can often
make no sense. Hint , DO NOT assume anything.

I've no problems with the first one, am I colorblind??? The second one is a mindfuck Anyway its something different than porn

+1 janjanjan, but i must say both are mindfuck , the first one just changing everytime i'm looking at it, sometime right, sometime left...

And for the second, here is the explanation :

This figure proves (if there was no tip) 64 = 65, but there is a trap ...
When we compare the two triangles, they appear identical. A quick
inspection, aided by the grid, shows us that we are dealing with two
triangles of 13 tiles wide and 5 tiles high.

In fact, the upper triangle is not a triangle at all, it is a quadrangle. If you
look carefully the hypotenuse (diagonal), you will see it is not quite right,
it is slightly concave. The lower triangle is not a triangle either, it is also a
quadrilateral, but this time the hypotenuse is slightly convex, since the
position of red and green triangles is now reversed.

Both figures are composed of the same pieces. But because the lower
triangle "has a hypotenuse which is convex surface additional vacuum is
the equivalent of a tile, so that's why the lower triangle has an empty box.

I hope this is clear, english is not my first language...

Here is a reason to vomit your coffee (i've got much more if you like this) :

babelfish? I translated it back to English:

gladly that my explanation has been meant to someone, and my first language is French…

and then to French:

heureusement que mon explication a été signifiée à quelqu'un, et ma première langue est le Français…

and to English again:

fortunately that my explanation was meant with quelqu' one, and my first language is the French…

Great Franky. I love these

Back ontopic, here's another.

this one is like the fameus Freud one.

I've got one - my left brain makes me look at the bush first......

Thanks for the link. But a question for those who still doubt: is the girl in your first post twirling to the left or to the right?

A silhouette only appears to pirouette or twirl. ( excuse my French )
In a flat image like this, circular motion is just inferred and ambiguous.
In this case if the sequence of 34 stills comprising the gif are played in
reverse the effect is the same and indistinguisable so there really is no
way to tell if this was even an actual person as opposed to an animated
drawing.

Some more impossible figures _
