At work (Stack Exchange) we use LESS. LESS is pretty good, especially compared to plain-jane CSS. This is a fun personal project, I think it has some neat ideas and may be solid enough for actual use; so I wrote it up and open sourced it.

I love the O'Reilly chart for demonstrating that http://oreilly.com/news/graphics/prog_lang_poster.pdf http://oreilly.com/news/graphics/prog_lang_poster.pdf [pdf].
