Yes, Higgie, and someone else too :wink:
It looks really nice, if it's appropriately lighted: a lot of light shining at it, but reflecting someting dark into viewer's direction (with the little mirrors that are under the digits) - it works outside on a bright day (sky deep blue = dark), but not on a cloudy day, and it doesn't work inside with good lighting and white ceiling (=office), or with overall poor lighting (=club, bar). IOW: in most situations readability is poor :(.
Scattering:
Active segments scatter the light, so they appear milky white.
Inactive segments are transparent, so you can look through them and see the little mirror below - you actually see what the mirror reflects. If this is something dark, it's ok. If it's white (like the active segments), you're doomed.
This can be seen very nicely
here on Peter Wenzig's site (just compare the 1st and 2nd picture).
Their advantage is that they are easier to make, no polarizer films required.
But then, the Microma DSM looks different - again Peter has a
nice example.
