There are lots of good use cases. The basement storage area of my apartment complex boarded up all the small windows for maintenance / security reasons, but I use my basement as a micro-workshop. Having a fake daylight simulator window would be excellent. Similarly my office has some small spaces that are perfectly sized for taking calls or having 1-on-1 meetings, but to depressing to sit in for more than an hour since there are no windows. A fake window is not a window replacement, but would make them nicer places to sit for small amounts of time.
