Right off the bat let me say that this is NOT one of those tricks where you stare at a picture for an extended period of time, then a screaming monster appears onscreen and scares the living sh*t out of you. (Sure sounds like something I'd do, but not this time!) It's just a cool optical illusion that you can do yourself with any of your own photos. If anyone wants to know how to do it, shoot me an e-mail and I'll send you the info I used.

Nice, that's pretty cool.

Amazing! I thought it might turn back to color if I looked back at the dot but once the color was gone it was gone for good. That was some crazy sh*t!

I stared at the dot for 30 minutes and now ... Well, I won't spoil the fun. Give it a try.
Very cool, Todd.

very cool todd. i have never seen this illusion used in that sense.

i learned about this in a sensation and perception class in college. if i remember correctly there is something similar to an auto white balance mechanism in the brain/eye. when you view an image like this for a long period of time and then look away the rods/cones get exhausted and try to correct themselves. i think...

Hmm, I must be doing something wrong I can't seem to get it to work.

How very interesting! Only you could come up with this trick in time for April Fools!

"I looked into the beam, Ray!" That is wild!

Really makes me think about the science of color and the mind. Thanks for sharing the experience!

Neat Todd!! I like the shot better in color, if only it would last. :wink:

That is the sickest illusion ive ever seen! Now--why does it work????
i notice it still works (though much less and faster transition) if you dont look at the black dot, so obviously the colors are training the rods/cones in some way. Neat!
