That's pretty cool, did you make it? Looks like some 3D software?

Stare at the dot

Those are so cool! :)

This one didn't do anything, how long are you supposed to stare at it?

Look at centre of this image

I think I'm dizzy now.

I never seen them guys in my life but I keep experiencing strange de ja vu's today.

Started around 9AM and I answered the phone twice...

Very strange day.

nice, I like the ones that look like they are spinning even though they aren't

great illusions!

Stare at the dot, then move your head forward and backwards

During the Optical Art (OpArt) Movement of the 1960s, artists would create all sort of puzzling effects with color. For instance, this "flashing squares" drawing seems to wobble and flash when you concentrate on one particular area of the image. How many squares can you see in this diagram? Can you feel the "motion" of the image?

1. The circles appear to be progressively lighter as you move to the right - but they're actually all the same shade of gray! (If you're not convinced, punch some holes in a piece of paper and place it over the picture to mask the background). Your brain tends to exaggerate the contrast between the circles and the background, so that the same circle appears darker against a light background, and lighter against a dark background.

2. Do you see the gray spots where the white lines cross? What happens when you look directly at them? Another demonstration of a contrast illusion.

3. The "wagon wheel illusion". The shape superimposed on the wheel is actually a perfect square, but it appears trapezoidal. Why? Probably because the converging "spokes" of the wheel provide strong depth cues.

4. Looking at this figure, you probably have a distinct impression of seeing a square. Now, cover up the "Pac Men" at two opposite corners of the square. What happens? This illusion shows that your brain performs pattern completion, and perceives complete objects, even when parts are missing.

Dude that is an Escher.

hehe, nice.. my brain is all fucked up now :winkwink:

nice thread. :thumbsup

Some of those were great, saved a few :)

that is sweet who did it

This one is my personal favorite. I actually printed it on a high qul. printer just because i thought it was a trick gif.. here it is in jpeg format
