Didn't put any detail in the post itself, but basically a window that I programmed with a time module and the Timelord functions to calc sunset and sunrise from Lat/Long. Then mapped color temp to time of day and outputted in a strip of LEDs around the window. Does some other things with a bluetooth module as well.
Didn't bathe the back of the wall with even light like I hoped, but had a short time to work on it from start to finish and done was done. Flow chart of program attached along with some pics, now in the original post.
