... I take the chance to mention here that I have 
just uploaded an image to my web site that shows an
example of how a normal BIC ball-point pen looks 
when illuminated with polarized light and then 
photographed through a macro lens with an attached 
polarization filter.

To view it, click on the 3rd hyperlink on this page:

I find these optical properties very fascinating.
