When I'm Sad My Computer Sends Me Cats

I wrote a program that sends cats to my phone when I'm sad at the computer. I was inspired by a tweet I saw last week. I've lost the link but, to paraphrase, it went something like this: I'm okay submitting myself to The Algorithm as long as it knows when I'm sad and forwards cats directly to my face I figured that you could probably solve this problem locally without leaking any personal data. Our computers are fast enough that we can run machine learning models in a browser in the background, maybe without even noticing. I went with vladmandic/human -- another strong contender was justadudewhohacks/face-api.js.
