Last night there was a thread that had images that messed with your eyes. One of the images was of a castle that was in black and white. After a second or so, it shifted to a weird colour, then counted down for about 15 seconds. Then the B&W came back, but it looked like it was normal colour... One of the spiffiest things I've seen, I think. I was going to show it to someone, but I only saved the link, not the picture... and now the link has disappeared. If anyone has this picture, could they post it please?

Also, this gif not related, but it is incredibly cute.

From my understanding it happens because the cones in your eyes that produce color vision tire out after staring at certain colors for a time, and the remainder try to compensate when you look at something else or the picture changes, in this case it reverting to black and white, and the unstimulated cones produce a negative image. Combining that with the black and white 'luminance' you get the illusion of a normal colored image.
