mick said...this one is from the very fine new blog ColorLovers. "See a new color you've never seen before!!...Well... at least never before on your monitor. It's a startling example of how poor the green/cyan element is on TVs and monitors generally. The colour you are about to witness is actually true Cyan ... a colour that is heavily diluted on the majority of monitors (thanks to colour pollution)." ***If you don't follow the directions, all you'll see is a little flickery coruscant of the colour*** so ... don't tell me if you cheat, ok? =)Directions: (paraphrased from the website)stare at the white dot in the centre of the red circle for 2 minutes. keep focused on the white dot. you'll start to see a thin rim of light around the edge. don't stop yet. wait the full 2 minutes, keeping your head still.THEN.. slowly...move your head backwards . keep your eyes focused on the dot. pause and move back slightly a few times. glory in that clean glow. this was the winning entry in an illusion contest, and is a nice example of the parallel lines illusion: "The visual system tends to treat two side-by-side images as if part of the same scene. However hard we try to think of the two photographs of the Leaning Tower as separate, albeit identical images of the same object, our visual system regards them as the â€˜Twin Towers of Pisaâ€™, whose perspective can only be interpreted in terms of one tower leaning more than the other."
If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour - pink. However if you stare at the black "+" in the center, the moving dot turns to green. Now, concentrate on the black "+" in the center 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. It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. Proof enough that we don't always see what we think we see...
