Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I have a rail line right under my apartment, so I built a small computer vision app running on a Rasperry Pi which records each train passing, and tries to stitch an image of it.

It has a frontend at https://trains.jo-m.ch/.

Edit: it's currently raining and the rain drops are disturbing the images a bit.

Really cool. They look like model trains! :-)

Yeah! I've never seen trains so clean and modern looking in my life. They look like they came out of a futuristic toy set.

They're swiss trains, I guess we have enough wealth to make sure that our trains are clean. The interior is also almost always clean, except early morning on weekends (drunk people).

From time to time I see a train with graffiti on it, but usually they remove such things very fast.

That's Europe for you. Usable train infra is actually a thing.

Maybe West Europe. Definitely not here in the east.

It somewhat works but let's not exaggerate how well it works.

There are visitors from the east sometimes ;)
