I didn't.  But, yes, I am aware of such a thing.  The trick is that it only
disperses *coherent* light, so that normal light is relatively unaffected.
The only drawback is that first surface reflections do make the visor act
like sunglasses to some extent.  It's great for daylight usage, but does
make things pretty dim at night.

Oh, it's GAWNE, not GWAYNE.  Pronounced like 'gone'.
