PowerPoint can also be used as an untended repeating loop display on, for example, an exhibition stand - and again this has evangelistic potential. PowerPoint can also be used as a cheap development tool for interactive CDs. You can build in a lot of interactivity using PowerPoint and embed just about any kind of video file including avi, mpeg, and even Flash. PowerPoint is not the best tool for CD-rom development, but can be used by a church or smaller ministry with limited resources. The final product can be fairly sophisticated and need not be linear in design.
Users can choose to watch a video or to see a still photo.
They can choose to click on an icon for more information about something, or skip ahead to a different topic. In function, this is just like a website that takes advantage of hypertext and other links. Most people are used to using PowerPoint for linear presentations, but this option is good for kiosk use or for building CDs that can be distributed for individual use. This is a cheap way of building a CD, but it gets the job done and avoids investment in expensive software. It is possible to build a fairly sophisticated CD just by using PowerPoint.
