I've been having a lot of fun with https://github.com/harthur/brain https://github.com/harthur/brain (neural network implementation in JavaScript) lately. Perhaps it's not something you would use on a real, live site, but it is fun to prototype neural network stuff in the browser with easy access to the DOM, canvas, and WebGL.
