There is a good example of a course paper (on Middleware), and good examples of course slides, sound, and PalTalk simulation (on Digital Imaging) below; done by two students in past classes.

Project Paper (Middleware)

Project PowerPoint Slides (Digital Imaging)

Project Presentation Sound (From PalTalk Session) (Digital Imaging)

Simulation of Actual PalTalk Presentation (streaming) (Digital Imaging)

The paper is in an MS-Word .doc file.  The slides are in an MS-PowerPoint .ppt file.
The sound is in a .wav file (uncompressed), and requires a Real or some other player for exercising.  Exercising the simulation (streaming) requires an up-to-date Java-capable browser (which you probably have).

The sound was recorded in a live PalTalk Internet conference; sound including questions and answers at the end of the presentation may been deleted so that the sound file could be made smaller.

The sound and slides can be synchronized by exercising the slides and sound links in 2 separate browsers, but you will need to synchronize the slides as instructed by the sound.  Alternatively, you can get the same effect automatically by playing the streaming version.

NOTE:  A PalTalk presenter requires a microphone for sound input, and full participation in a PalTalk presentation by a non-presenter requires microphone input.
