Elena had a simple problem that turned out to be surprisingly hard to solve.
She had twenty-two years of digital photographs — somewhere around forty thousand of them, organized into yearly folders on an external hard drive attached to her MacBook — and she wanted them to play on her living room TV. Not in a slideshow she had to launch manually. Not in an app that required her to import everything into its own library and give up her folder structure. Just... playing. Continuously. On the TV. The way a screensaver plays on a monitor, but on the television, and with her actual photographs.
She was not what anyone would call a technical person, but she was a practical one. She had looked into this. Apple's solution required iCloud and a monthly fee and reorganizing everything into Photos, which she did not want to do. Google's solution had the same problem plus privacy concerns that made her uncomfortable. Plex — her brother-in-law had mentioned Plex — turned out to require more setup than she had patience for and was designed around movies and TV shows, not family photographs. Roku had a screensaver feature but it showed generic landscapes, not her family.
What she wanted did not seem to exist. She almost gave up.
"I just wanted my photos on my TV. I didn't think that should require a computer science degree."
She mentioned it again at Thanksgiving. Her brother-in-law — a different one, the quiet one who actually enjoyed this kind of thing — said he thought he could help. He came over the following weekend with his laptop.
He installed something called Docker Desktop on her MacBook. She didn't need to know what Docker was, he explained, any more than she needed to know how her refrigerator's compressor worked. It ran in the background. Then he opened a browser and went to an address that looked like a website but was actually running on her Mac, and he typed in the path to her external hard drive, and MemoryStream went away and catalogued her forty thousand photographs.
It took about twenty minutes. She made tea.
When it was done, he opened the MemoryStream app on his phone — she downloaded it herself on hers before he left — and he pressed Play. The television, connected to her Roku via a small AirPlay button on the app, began showing her photographs.
Not a random selection. Not the most recent ones. All of them, in a carefully randomized order that would, if she never touched anything, take months to cycle through. Her daughter's first birthday. The trip to Portugal in 2011. The dog they had before the dog they have now. Her parents' fiftieth anniversary dinner. Her own face, much younger, laughing at something at a party she can no longer quite remember.
The app on Elena's phone has one main screen when the slideshow is running. There is a play/pause button, a skip button, and a settings button. That is essentially all she uses. She has never opened the settings.
She can tell the app which folders to include or leave out — she excluded the folder of photographs from a trip with her ex-husband, which took about ten seconds — and she can adjust how long each photo stays on screen before moving to the next one. She likes eight seconds. Her daughter, when she visits, changes it to five. The app remembers each person's preference separately.
"My daughter changes the settings when she's here. The app knows it's her. I don't have to change anything back."
The photographs pause automatically when the television turns off. They resume when it turns on. She didn't configure this. It simply works.
She has since added her music. Her MacBook has a folder of MP3s and ALAC files — not as many as some people, perhaps two hundred albums — that MemoryStream found and catalogued the same way it found her photographs. She sometimes turns on Paired Mode when she's in the living room in the evenings: the photographs on the television, her music playing through the room's Bluetooth speaker via her phone, the occasional quiet announcement about what just played. It feels, she said to her sister, like having a very nice apartment.
Elena had told four friends about MemoryStream by the time she was asked to read this document. Her description was consistent: "You know how you have all those photos but you never look at them? This just shows them. On your TV. All the time. You don't have to do anything."
The question she always got was: is it complicated to set up? She said honestly that she hadn't set it up herself — her brother-in-law had done it in an afternoon — but that it had worked perfectly since then and she had never needed to touch it except to download the app. The photographs kept showing up. The music kept playing. Nothing had broken.
What she didn't say, because it was harder to put into words, was that the experience had changed something subtle about her living room. The television was no longer a dark rectangle waiting to be switched on for a purpose. It was something else — a window into her own history, open all the time, available whenever she glanced over. Her life was playing on the wall. The dog was still alive in those photographs. The kids were little. Her parents were at the dinner table.
She keeps the slideshow running almost all day now. She doesn't always watch it. But it's there.
