LCD monitor, I was able to look back and forth and continue to see the illusion for at least 15 seconds, at which point I closed the window. It didn’t seem to be going away.
15" LCD MacBook Pro screen. Stared at image for 30-40 seconds. When I clicked back, the color image appeared and stayed for 10-15 seconds. The trick is to keep looking at the dot in the center. The moment you avert your gaze, it becomes grayscale.
Oh great, now you tell me. What the heck. if I don’t avert my eyes, I won’t get to enjoy the colors over the entire photograph.
What a lousy trick !!!

I’m sure that’s how it’s done, in fact, because when I recombined the image based on the above assumptions, I got this.

Nice!
But where are the French taunters?

It was a cool effect but it only lasted about a quarter second for me.

Are you keeping your eyes focused on the dot? When I look elsewhere it goes back to b/w, but when I concentrate on the dot again, it becomes color, and this effect obtains for many seconds.
Oh, and I have one of those big 'ole desk-top monitors.

I dunno about French taunters..
Two facts you should probably know about the castle in the images are:[ul]
[li]It’s Manzanares el Real, just north of Madrid.[/li][li]It was built by the Mendoza family in the 15th Century.[/li][li]One of the Mendozas became a Cardinal, devoted to Queen Isabella.[/li][/ul]Sorry, make that three facts you should probably know about the castle.
It’s just possible that if you look carefully at the image of the castle, you might be able to see (but probably shouldn’t expect to see)
THE SPANISH INQUISITION!

Brilliantly understated.
I actually put an extra few hundred bucks into our new medical-savings account at work just so that I could get a prescription pair of flight goggles like this. Yeah, it’s nuts, but it must be done! Heh.
(Heh, I had to make the text black so the link wouldn’t be so obvious, but the underline still shows up. C’est la guerre.)
Too cool!
