Clock display with Apple TV homesharing photos

I have an app called Peaceful Clock (!) that is neat for using the AppleTV as clock display. The scenes are “peaceful” but I would prefer to be displaying photos from my Homesharing Mac. There doesn’t seem to be a way to do this. Has anyone come across a suitable app?
I suppose I could request adding a clock display option in feedback to Apple but I think I would be wasting my time (Homesharing eats into Apple’s subscription revenue!).
Maybe I should become a tvOS app developer and make my fortune :blush:
