    Dr. Young has just published 3D images of 130 different species of
    cephalopods, in 43 different families on the Tree of Life. I recently had
    the pleasure of being a guest at Dick's house and previewing some of his
    many images and was very impressed with the quality, 3D approach and species coverage. To see these images for yourself, go to:

    http://tolweb.org/articles/?article_id=5274

    To learn more about cephalopod beaks and the terminology used to describe
    them, see:

    http://tolweb.org/articles/?article_id=1980

    To view these images in 3D, you will need glasses with red and cyan lenses
    (filters) – such as these:

    I've only got one good eye, but the collection and work look impressive. Thanks!

    This is WAY cooler than I thought it would be and I thought it would be great!

    L_H, My son is very color blind so I am curious to have him try the glasses to see if he too is excluded from this adventure.
    Do you have any sight in the other eye that allows vision with corrective lenses? There are inexpensive clip ons if this is the case.

    For more ceph images (I had to find something else to look at) try this site. No where near the quality but a use for the glasses :grin:

    There is some vision now; the retina has reattached after a number of surgeries. But it's poor, and uncorrectable, as the problem is at the "film" rather than the "lens" part of the process. Picture a new sheet of aluminum foil, nice and smooth. Wad it up, then try to flatten it out again; it will forevermore be sort of "faceted." That's the effect I get, ignoring the low-resolution aspect of the image.

    In any event, I expect that your son won't have any problem with the 3D images; his color-blindness (depending upon the specific nature of it) might actually make this work better for him than for most people. The 3D trick involves filtering (and color-shifting) light at the glasses; each eye thus sees a different result, and is not required to interpret color cues for it to work.

    I hope it works for him -- this is a very impressive (and extensive) resource, and the odd shape of the beaks (particularly the part within the buccal mass) is hard to conceptualize without this sort of view.

    My brother-in-law has a perferated retina condition in both eyes and for awhile we did not know if the deterioration would be stopped. It went into remission 20 years ago (with medical help) and I don't think it has gotten worse in the last 10 years. I am not sure if they ever tried surgical intervention during the process but he has no sight in the center of his eyes. He can still read with difficulty, thick glasses, lots of light and holding the material off center but it is a major chore. He drives but probably should not. I don't know if they ever came up with a reason but I suspect genetics on his father's side as his uncle was all but blind for many years and my husband has only light perception in one eye (correctable with glasses and not involved with the retina but still a biologic eye issue).

    ... as it so happens, I'm just about to start working with Dr. Young.

    I quite like this one (prob cos I'm in the Southern Ocean!)
