Rendering equations on the web: MathJax

Previously I've mentioned codecog's online equation editor, which is pretty useful for generating images of LaTeX-rendered equations for use in web pages and powerpoint presentations.

Thanks to the latest version of doxygen, I've just discovered something even more useful: MathJax. It is an open source javascript display engine for math than works in all modern browsers, supports LaTeX and MathML, and allows copy and paste into LaTeX, Word, Mathematic. Wikipedia etc. Pretty amazing.
