Because light diffuses over distance, something as small as the grate you're shining through would blur to one solid light square by the time it hit the ground... if you wanted something to realistically cast that light/shadow on the ground, it'd probably have to be at least 4ft square or so.
An exception to this is in atmosphere-less environments, where there are no air molecules to scatter the light - shadows remain crisp (e.g. on the moon).
I think it's a great idea! Why not play with a light in a recess in the ceiling, 5 feet or so above a large grate set in the ceiling? That'd make for a nice (and more realistic) shadow.
What I really want to know is if that is real light, or if it is an overlay texture. If it's real light, I'd really like to know how you are doing it. Inspired by Doom3 shots, I set out to to the same thing in my own level, but I can't get narrow bands of light without creating a mess out of the level. Thus, I've settled with a totally different/unique appearence, which I'm totally satisfied with, but would still like to play with narrow bands of light some day. Thing is, I need real light, not overlays.
Is that real light from spotlight entities? Or is it a texture overlay? I was certain it was an overlay when I first saw it, but after looking harder I'm not so convinced it is anymore...

the yellow lines indicate the size of the square that should be made given the sheets of light coming from the light. green shaded area gives the size of the sheets of light that would need justify that large of a light pattern.
just for future reference... if you were to create a pyramidal brush with the base at the texture over-lay, and the top poiting through the roof to the point where at the intersection of the pyramid with the roof creates a square the same size as the light.... then cut off the top of the pyramid so that it's flush with the light, and then cut the bottom of the pyramid off to the length that you want the sheets of light coming from the light to be (cut, don't stretch, otherwise you'll lose the proper angles and sizes of the sheets and it won't work), and texture, it'll look realistic.
oi! wot a lot O woids.
BUT i very close to duplicating it with real light. i think the new built-in zoner entity light_origin may work for this effect but i am still working on it...
