What is it?

Microsoft Powerpoint is a popular computer presentation program (think "digital slideshow"). It is most commonly used to present ideas and images in a linear sequence. It is fairly easy to learn to use Powerpoint to make simple "click-through" slideshows to present your work. The program also has more advanced features that create animations and non-linear "interactive" possibilities.

Powerpoint is available for Windows or Macintosh, and in theory it is possible to bring your files between platforms. These files have a .ppt extension. Similar programs which may both open and export Powerpoint files are Apple Keynote (only on Mac OSX) and OpenOffice Impress.
