So I came across this gif today... It's absolutely awesome! I can't explain it. Does anyone know how it works? If so, we should make our own!

So, I've been messing with it more... If you stare at an inverted pic for a while then stare at the desaturated image your brain can fill it in correctly. It's crazy!

Woah! How the hell does that work!

Nice link!

Here how I think it's done. many frames and the second to last one is in colour for a split second then the last one is desaturated. The dot and the time bar are the distraction.

@bneises, nice sign you have there! Tell me all about this Fearless Roll please!

Oh... nice giffy... it's all in the mind I think.

It is really rather simple - I hate to tell you and ruin the magic act!

So, whenever we stare at a coloured scene for a period of time, the rods and cones in our eyeballs retain some of the image... BUT it is INVERTED. This is why, if you look at a bright light or the sun and then look away you'll see a black spot where the bright light just was.

This also happens for colours too. So by staring at that original image for 10 or 15 seconds, and then TURNING IT TO GRAY fast, the after image is REVERSED from your eyeball nerves - and you see it in its "original" colour for a few moments. The thing that makes this work well is the fact that the reversed colours are SUPER SATURATED, so they really "burn into" your eye nerve cells. If you INVERT the colour of the original GIF image, you'll see that the "red" of the wall bricks is very strong.

Cool, eh?

I had to try it.
I inverted the color and upped the saturation on one and grayscaled the other.

kinda works I think......

Wish I knew how to make a gif.

Is it an optical illusion just like this?

I was staring at the image for minutes and waiting, nothing happened

Yeah - that's what I'm talking about.

There are some pretty amazing illusions out there on the web... you could spend DAYS of your lives looking at them all. And when you are done, you'll fell SLEEPY and you'll DO MY BIDDING...
First up - BRING ME A BEER! }

Yes, I had to try make an optical illusion as well:

Yeap! Damn.......

I knew it!
TG, no sound effects

It works all the time. Last week it was explained in a tv programme how it works.

Your brain takes in the black dot in the coloured surroundings, and tries to make coloured sense of it. Then, when you show the image in black and white, your brain is overstimulated to colour everything black and it works for the whole black and white image.

The same way you can trick your brain to look at a hollow image and see it as a 3d image when you start moving it around.
