    I know I've done this sort of thing before, but can't quite get it
    today. I assume there is some emboss and polar coordination involved,
    possibly some layer styles, but how does one get this effect?

    At first glance, I don't see many shortcuts to create this image with
    emboss/lighting effects. There are 66 lighting directions; one for each "saw

    If you look closely, each tooth is identical in shape, rotational
    orientation, and highlight direction. The difference between teeth is a
    polar movement of 10 degrees on the outer ring and 12 degrees on the inner
    ring. You may have to create 66 layers and rotate each one.

    That particular image is a very well-known optical illusion.

    My bet is that if you wanted to recreate it the first step would be to
    create a line drawing in Illustrator.

    I think you're right about the emboss filter having been run in PS.
    But note that the highlights and shadows are on different sides in the
    inner circle than they are in the outer circle. So one click of the
    filter on the entire image is not going to accomplish the final
