Howto: Get nicely rendered LaTeX images online

I decided to use mathtex. It's a nice program indeed, but it needed some tuning for my needs:

1. By default, LaTeX does not play nice with non-english letters. I fixed that by throwing in a pile of \usepackages.
2. I hate black-on-white scheme, so I made a modification to source code to allow changing color of rendered formulas on compilation.

You can see the results here: [http://dump.bitcheese.net/xet/mtex.cgi?yourformulahere]. Change mtex to mtexi for inverted output.

You can use this online LaTeX equation editor (on in russian), or this fast and lightweight previewer without any AJAX or JavaScript.
