How may take a really close look at the swarf they produce?

I was cutting some rings from the face of 6" brass round
http://webpages.charter.net/dwarner2/Rings.JPG
for a clockmaker / co-worker, and was (easily) impressed by the
variety of forms the cuttings had, from the .063" wide flat sprials,
to dust particles, to wispy fluff.

I decided to take a macro shot of the stuff before disposing of it,
and posted this large (2.7MB) photo to scroll around it.
If your web browser shrinks it to fit the screen, expand it to full
size to see the full range..

That photo would make a very nice Windows desktop wallpaper.
