to be painted by Jeff, taking care to note the orientation of the fabric when he is finished and ready to return to me. Jeff would tailor his painting depending on the fiber optic star layout I would provide. I would then adhere the fabric on my MDF panels for the fiber optic installation. The plus side is that it saves the expense of Jeff having to travel to your home. The downside is that the paint has a standard glow-in-the-dark yellowish color that could be easily seen against the black with the naked eye and, more importantly, it was not something Jeff had done before. In other words, he was used to painting on non-fabric surfaces as you might imagine. Throw in the fact that the number of UV lights you need to sufficiently charge the ceiling can start to add up from a cost perspective and you can see where I started to abandon the idea or merging the two systems before I even got started. It still would be interesting to see someone try.
The other point Jeff had mentioned before is if you had the ability to create a slight barrel to the ceiling, the stars will charge more evenly and not be brighter on the sides than in the middle where the light is a bit more diffuse.. I would have loved to create a barrel ceiling, but I am already restricted on headroom and that would have killed my soffit design.
With FOSI's fiber optic system there is a way to make the constellations MUCH brighter and be in the astrologically correct positions in the sky as they specialize in planetarium work for commercial projects. About 28 seconds into this video you can see how they can highlight the constellations:
Ah, in watching the video, I think the painted ceiling is definitely enough for me. I really like the comet effect though...I'm thinking I can add a few thin diagonal strips below the painted ceiling with just the comet lights installed. they would have to curve to avoid the major elements of the painted ceilings, but that would give the comet a fun path anyway.

I then draped some cut peices over both Submersives and LR JBL towers. It begins to show reflective properties at 1khz. It can be a good thing in trying to control the liveliness and deadness of a room.
Ah, interesting. So this would be in conjunction with items like linacoustic? or instead of? Or is this what you wrap your treatments in? I know this is your wheelhouse, and I find this very interesting.

Also, a 179 In. diagonal 16:9 is 13 feet wide and 7 ft. 4 in. high, or 95 sq. ft.. My 12 ft wide screen would be 81 inches high in a 16:9 aspect ratio, or equivalent to 81 sq. ft. So it takes 17% more lumens to get the same screen brightness on a 13 foot wide screen.
Bottom line, as far as I know, Stewart is the only game in town if you need an AT screen with gain.
Hmmm, woven screens' claimed gain is generally inaccurate? That's news to me--I'm getting ready to check out some of those tests. I"ll also chat with Rich from Falcon Screens to verify that his screens have gain. Very interesting information...

How are you utilizing that fabric in your theater? Soffits, like Jlpowell?

Ah, so the material is good for bass traps, but something like GoM should be used for the first-reflection points?
