LyX: the WYSIWYM document processor

I'm always glad to see there are clever projects providing alternatives to boring WYSIWYG word processors. LyX is one of those. It defines itself as a "What You See Is What You Mean" document processor. LyX is a graphical environment for typing LaTeX-like documents. Text displays nicely with various font sizes and so on, but does not attempt to match exactly the final result, so it can display useful tags and so on. LyX documentations coins a few interesting terms: "WYSIWYM", "document processor" instead of "word processor" and "finger painting" for this boring way to set style at character level under a graphical user interface. LyX requires TeX. Check the demo video for mathematical equations, it rocks.
