This thread's taken a on a life of its own that I never expected.
If you want to see this effect in action, you need two pairs of polarized glasses. Stack them one on top of the other and look through them at a light source. While looking, rotate one lens against the other. If you have two good polarizers, at one orientation, you will see 100% (or very nearly) blockage of light.
It's this orientation manufacturers should try to avoid.
