A 3D Texture-Mapped Globe Rendered with Javascript and HTML

I've been working on a large-ish Javascript project lately (still in stealth mode). One that could be described as a Javascript application. And since I've been up to my elbows in Javascript, I have found my contempt for the language waning. Not entirely, of course – I'm still a Python fan-boy. But enough for me to knock out a 3D(ish) spinning texture-mapped globe, using nothing but Javascript and HTML, as a way of honing my JS skills.

Without further ado, I present you with a 3D Javascript Globe.

This effect is off course a hack in the sense that it produces a novel result, but it still only makes use of standard browser capabilities.

BBCode Ajax test server

Since I have some time on my hands, I've been doing a little work on Postmarkup - my BBCode module. I've made some significant improvements to the design which fixes a few issues and makes it easier to create new tags. To test it, I hacked together a simple web-app using CherryPy, which allows you to edit bbcode in the browser and see the resulting html update live -- with a little Ajax magic.

Please give it a try, and let me know if you can break it.

In building this, I've created a very rudimentary web service. I'm wondering if there is any practical use for such a thing...
