I have one Synology DS220+ at my parents house which I use for offsite backup of the computers and phones mostly. But it also runs Synology Photos which does face recognition which I then use to once an hour to fetch 20 pictures of pictures with the family on to show on the TV in the living room. I have pictures there dating back to 2004 which makes it a very cool walk down the memory lane. And I can use the TV as a big interactive picture frame when nobody is watching anything but we're at home.

With a similar script I also post pictures like "Today n years ago" in two of my family chats which is even cooler because there my siblings and parents also can one picture from n years ago every day in the morning when they wake up.

Here is the script, the bad part is that it has to have access to the postgresql database on the NAS, so it's a bit tricky to set up but once it runs it's awesome! https://github.com/jeena/synology-pictures
