    I don't believe its actually changing. There's nothing in the source for
    that page that makes it change.

    Yes, there is a difference between the two photos. There is a little
    Unbelieveable! I did exactly what you did, and looked at a small section
    every time but couldnt see the difference. After reading your description
    though, I spotted it first time - its so obvious (I was just about to split
    the animation into the two frames and stereoview them to spot the 'floating'

    it is an animated gif which automatically changes - no code is needed :)

    You have just helped Hoffman prove his point--that most of us ARE
    blind to small changes in the visual field.

    Look in the area of the lower right-hand corner. There is a
    somewhat thick, nearly horizontal green stem. From that one, another
    stem, thinner, extends upward, leaning slightly to the left. On the
    left side of that stem there is a clump (flower?) of material that is
    present in one view and not in the other.

    Me too - I didn't spot it, despite concentrating on little segments - I cheated
    by looking at the animated gif in photoshop. Grrr :)

    Hi Francine,

    The reason I didn't read your post is because it wasn't there. When
    I submitted my post, there were only two others on this topic: Martin
    Eden's and Scott Seidman's. As you no doubt know, there is a time lag
    between the time a post is submitted and the time it actually appears
    on the forum. Often it takes many hours for a post to appear.

    Obviously, if I had seen your post there would have been no need
    for me to post, since we both said essentially the same thing: that we
    discovered the difference between the two fotos.

    As to character defects, that's not so serious. I only wish that
    the ones I have were as minor as that! :)

  8. There can be long time lapses for readers, as well. Usenet posts generally
    bubble around the world, passing from place to place. It doesn't go from
    your computer to a master server to pass to every server from there--it can
    propogate slowly.
