We thought it might be nice to be able to light the windows in the attic with colored lights – and change the colors as well. As a starting point, we got an internet controllable light from http://www.lifx.com/. But since we had 5 windows, we hoped to just point the bulb up, and bounce off the walls. Alas, the attic had never been painted (not counting some tests from 20 years back)
Poked around in the basement and found some leftover paint. Since the goal was just to reflect light, a quick paint job on most of the upper surfaces should be enough.
Maybe someday we might do a second coat, but for now, this seems adequate .
