curtains.js is a lightweight vanilla WebGL javascript library that turns HTML DOM elements into interactive textured planes.

Shaders are the new front-end web development big thing, with the ability to create very powerful 3D interactions and animations. A lot of very good javascript libraries already handle WebGL but with most of them it's kind of a headache to position your meshes relative to the DOM elements of your web page. curtains.js was created with just that issue in mind.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
