three.js and JSFiddle

Here's a small web toy, as a test of embedding a client-side visualisation in this blog. The toy written in JavaScript using the Three.js 3D graphics library, and is hosted at JSFiddle.net. If you click the "Edit in JSFiddle" link, you'll go off site to a full multi-pane view of the toy, where you can inspect and modify and play with the various parts of the HTML, CSS, and JavaScript.
