I have found the best free plug-in for the PC since Dave’s Quick Search Deskbar: the Powerpoint add-in, TexPoint. If you’ve ever typeset a formula in LaTeX and imported an image of it into Powerpoint as a TIFF, or spent hours cursing at the Microsoft equation editor while preparing slides for a paper you’ve already formated to death, you’ll love this. Install this tool, and you can type LaTeX source right into your Powerpoint slides and convert it to the corresponding display form. I’ve only played with it a little, but I’m in love. [Many thanks to J for pointing this out and test running its usefulness!]
