Simulating Raindrops Falling on a Glass Surface

Rainyday.js is a simple script for simulating raindrops falling on a glass surface. You can get that meditative feel of watching rain on your window right in your browser. Hardly practical by any definition, but it’s quite fun to watch.

The idea behind rainyday.js is to create a light JavaScript library that makes use of the HTML5 canvas to render an animation of raindrops falling on a glass surface. Simple enough, yet challenging at times, especially since it’s trying to avoid that cartoonish look usually attributed to JavaScript animations and at the same time make sure the animations work smoothly.
