I installed a dozen of these 35 years ago in my last wife's painting studio. She wanted to paint at night in daylight. I sprayed the entire space in matte eggshell white. I also worked at night.

On a snowy night, the windows glowed like a spaceship.

She painted Rembrandt style using traditional methods. Modern sitters.

RIP Marnie.
