Perhaps both. I also saw your second post and while that works, I was looking for a different effect. That effect being displaying a single sheet of glass that is somewhat movable. And while my solution is scalable (one sheet or even multiple sheets) the size (height and width) is always that of the glass, plus the frame edge.

Moreover, bulb replacement (which happens for fluorescents) or worse, a ballast replacement, requires removal of the displayed glass and sometimes the entire fixture.

Thanks for the comments.
