IguanaTex is a PowerPoint plug-in which allows you to insert LaTeX equations into your PowerPoint presentation. It is distributed completely for free.
If you know how to use LaTeX, it is very easy to use IguanaTex. Select New Latex Equation from the Insert menu, and you will get a dialog box where you can type your equation:
Type any valid LaTeX code, and click on Create. IguanaTex will compile your code into LaTeX, create an image from it and insert it into PowerPoint.
Need to change something in the equation? Just double-click on the image, and the IguanaTex dialog will re-appear so you can edit the LaTeX code; or, select the image and choose Edit Latex Equation from the Insert menu.
You can also treat the equation as an ordinary PowerPoint image. For example, it can be animated, rotated, moved, and resized.
When you save the presentation, both the image and the LaTeX code are stored. This means that you can display your presentation on any computer, even computers on which IguanaTex is not installed (no more missing fonts!). Of course, equations can only be edited if you install IguanaTex.
Download IguanaTex here. The current version is 1.04.
After downloading, double-click the .msi file to install, then follow the instructions on screen.
