Reaction GIF Generator
Just for fun, I built a small app in Vue.js that allowed you to take a selfie to find an appropriate reaction gif. It ended up getting featured on websites such as Mashable.
I built it using the Oxford Emotion API, the Giphy API, and HTML5 webcam access
Unfortunately, free access to the Oxford Emotion API is no more and so the app is no longer working, but here's the front-end code.
