Trivially easy inline LaTeX anyone? How about some beautifully syntax-highlighted lisp? Right monitor is the code I type; left hand side shows the result on the web server when I hit C-c C-e P. Ideally I wouldn’t be using MathJax because it’s evil JavaScript, and I’d be using org-mode’s capability to generate images instead, but I’m experiencing some weirdness with that atm that I haven’t yet managed to fix.
