    I had other reason to look in one of my favorites folders, and came
    upon this link. I've used it for years, but then I realized that
    Orchidians would find it equally as useful, both for educational
    reasons and sales purposes. This is a Russian website, what you
    might call a scientific site, meaning that it's nationality has no
    meaning, and there is much collaboration with other parties included.
    The link I am providing goes directly to the ray-traced models, but
    if it doesn't work, you may have to navigate there by yourself - it
    is the cut-study, and ray-traced models. And you will need to install
    the Active-X control when you get there (It will tell you) It is
    various animations, on several pages, of the passage of light through
    a cut diamond, and then there are controls to change the stone. So,
    you can start with an ideal cut diamond, and it rotates and shows the
    passage of light, and then widen the table and see what the change
    does then - also the girdle, pavilion, etc. Very fascinating, and
    there's also much other data scattered around for those who want to
    know - Tolkowski's original calculations, for instance. Be aware that
    it is 1/2 in Russian, not very user-friendly, and a little funky, but
    there's a lot there. The ray-traced animations are just great,
    though.
