Hello all -
Me again. Hope it's ok to start two threads in one day.
I'm trying to change an ordinary round window (about 30" in diameter) into a glowing moon, where the moon is visible from both sides. I've seen posts about people building moon boxes our of plywood, with hidden LEDs making an acetate moon image glow from behind. This wouldn't work for what I'm trying to do. Instead, I'm wondering if I can buy a custom printed acetate moon image (30" wide), affix it to the window, and then shine a light on it from one side. It would glow on the opposite side, and be illuminated on the first side.
The trick is in figuring out what light to use. To avoid keystoning, I could install the light directly in front of the window (there is a hidden cover that would work for this purpose), but I'm not sure how to get the light to the exact diameter I need. [If it's bigger than the window, the effect will be spoiled on that side.] It needs to be a wide-angle beam, since it's about a 4' throw to a 30" wide circle. Is there a wee little light available someplace that I could stick in the cove, point at the window, and adjust the zoom until it's exactly the right size?
Finally, while I can call around to see who can print out 30" acetate prints, I'm at a loss of where to find a high-def image online that I can download for the print job. It'd have to be a rather large file to show reasonable detail in a 30" wide image.
You guys are great problem solvers -- any thoughts?
Thanks!
