Who uses K to voice chat though? That’s so far from your hand, I usually just use one of the mouse buttons or something.

That looks more like an attempt at crowd assaulting than crowd surfing.

Asshole…

Okay heres one that will blow your mind

The squares A and B are different shades of grey right?? WRONG, they are infact exactly the same colour, don’t believe me? Use the colour picker in photoshop and see for yourself.

I’ve tested it, still can’t get my head round it o_O

How is square b lighter than square a when it’s sitting is the shade?

I do believe the MIT website has the answer to this illusion:

[SIZE=4]

Why does the illusion work?

http://web.mit.edu/persci/people/images/pixel.gif

The visual system needs to determine the color of objects in the world. In this case the problem is to determine the gray shade of the checks on the floor. Just measuring the light coming from a surface (the luminance) is not enough: a cast shadow will dim a surface, so that a white surface in shadow may be reflecting less light than a black surface in full light. The visual system uses several tricks to determine where the shadows are and how to compensate for them, in order to determine the shade of gray “paint” that belongs to the surface.

http://web.mit.edu/persci/people/images/pixel.gif

The first trick is based on local contrast. In shadow or not, a check that is lighter than its neighboring checks is probably lighter than average, and vice versa. In the figure, the light check in shadow is surrounded by darker checks. Thus, even though the check is physically dark, it is light when compared to its neighbors. The dark checks outside the shadow, conversely, are surrounded by lighter checks, so they look dark by comparison.

http://web.mit.edu/persci/people/images/pixel.gif

A second trick is based on the fact that shadows often have soft edges, while paint boundaries (like the checks) often have sharp edges. The visual system tends to ignore gradual changes in light level, so that it can determine the color of the surfaces without being misled by shadows. In this figure, the shadow looks like a shadow, both because it is fuzzy and because the shadow casting object is visible.

http://web.mit.edu/persci/people/images/pixel.gif

The “paintness” of the checks is aided by the form of the “X-junctions” formed by 4 abutting checks. This type of junction is usually a signal that all the edges should be interpreted as changes in surface color rather than in terms of shadows or lighting.

http://web.mit.edu/persci/people/images/pixel.gif

As with many so-called illusions, this effect really demonstrates the success rather than the failure of the visual system. The visual system is not very good at being a physical light meter, but that is not its purpose. The important task is to break the image information down into meaningful components, and thereby perceive the nature of the objects in view.

Now an actual contribution:

edit: ^^ or what he said/pasted

???
It’s not. they are the exact same shade… There was an episode of bbc’s horizon about optical illusions that featured this and other similar illusions.

heres another one that i think is even crazier…

The cross section in the middle of both objects are the exact same shade of gray, even though the one in the yellow box looks blue and the one in the blue box looks yellow. In reality, both are simply gray.

I feel like you guys just told me god doesnt exist.

…So confused right now.

Phantom_Angel · September 28, 2011, 5:31am

If you tilt your monitor and/or look at it from an angle, you can see that they’re the same color.

Okay try this. Cover up the squares around both the A and B squares and really look at them.The A square will look lighter and the B square will look darker.

I cracked up laughing when I saw this.
