Lee makes the most brilliant suggestion - what about MLC's Privacy Film. This I have used. Download the mesh from MTS
So 3 Stained Glass windows...
They've all been made to work with a single tile full length window - so Numenor's Wall Window or StoneTower's Modern Fullsize Windows works well with them. Other's will cut some of the design off, but if you're ok with that. They still look fine.
MLC has repositoried her set, so that there is a short version and a 2 tile version that can also automatically be used. The short version doesn't really look right, but the 2 tile does.
The Privacy film can be found under Deco -> Curtains.
These designs were chosen for my dorm in Karen's Campus Constructors Contest.
Half-Life and Physics are from the Interweb and Google.
The Magic Square is my copy/homage of the :
"Stained glass window in the dining hall of Gonville and Caius College, in Cambridge (UK), commemorating Ronald A. Fisher, geneticist and statistician, who was a fellow and president of the college. The window represents a 7 by 7 Latin square, an experimental design used in statistics; the text on the windows reads: R.A. FISHER; FELLOW 1920-1926 1943-1962; PRESIDENT 1956-1959."
I'd like to note, however, that the CEP was NOT made to fix AL blunders specifically. Because that would indicate that EA didn't make mistakes before AL. They DID!!!
But actually, CEP has been around to make certain non-recolorable objects recolorable! And such has been needed from the moment the Basegame was released.
