About Snowworker Snowworker is an easy to use snow effect for websites. Behind the scenes it uses a worker and a sharedArrayBuffer to keep things moving quickly, so it shouldn't block your UI thread. Many thanks to unpkg for being a CDN.

Using Snowworker Add https://unpkg.com/snowworker@1.0.9/snow.js to you page in a script tag. If you want snow to settle on things give them a .rooftop class. Star the repo: https://github.com/onion2k/snowworker
