I make glass differently than most of you. I'm less concerned with perfect realism than an artistic impression. In some applications I pump up the colored effects that this material only hints at. I also take glass towards being a little brighter than reality. This helps it 'feel' right more than look exactly like a photo of a glass object.
When making glass railings for example, you really don't want the glass to be too transparent, you want it to feel a little solid so viewers know something is there at the edge of the balcony. Therefor, you go slightly lighter or darker. I choose lighter, though reality would suggest darker due to less than 100% transmission of light through the glass.
This material is somewhat slow to raytrace. When used as curtainwall vision glass it would be best to exclude glass from GI and turn off shadow casting (though i did end up beating the shadow problem I was having with this material (described in another thread)).
For the box-o-panes image I turned off the text on the scene box because they were distracting as reflections.

Enjoy, suggestions welcome.
