IguanaTex is a PowerPoint plug-in which allows you to insert LaTeX equations into your PowerPoint presentation. It is distributed completely for free, along with its source code.
If you know how to use LaTeX, it is very easy to use IguanaTex. Select New LaTeX display from the IguanaTex tab of the ribbon, 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 select the image, then click on "Edit LaTeX display" in the IguanaTex tab of the ribbon, and the IguanaTex dialog will re-appear so you can edit the LaTeX code.
You can also treat the equation as an ordinary PowerPoint image. For example, it can be grouped, animated, rotated, moved, and resized. Further editing of the equation will preserve all these changes.
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.
If you were a TexPoint user, rejoice: you can now (v1.40+) use IguanaTex to edit your TexPoint displays, which will be automatically converted to IguanaTex format. You can either edit a TexPoint display as a normal IguanaTex one as described above, or just select one or more TexPoint displays (or the slides that contain them) and click on "Regenerate LaTeX displays" to convert them to IguanaTex format.

IguanaTex is free, but if you like it and would like to show your appreciation, I encourage you to donate to the non-profit Union of Concerned Scientists through my IguanaTex Fundraising Page. (Note: absolutely nothing goes to me)
The Union of Concerned Scientists "puts rigorous, independent science to work to solve our planet's most pressing problems", first and foremost global warming.
Let's all be concerned scientists!
The current version of IguanaTex is maintained by Jonathan Le Roux. It was expanded from the original version, written by Zvika Ben-Haim, mainly to add support for groups and formatting, then later many more features. See the changelog for details. The current version also includes a modification by Hammad M to make the IguanaTex editor window resizeable (see details here).
