Do you know about Zentation? Zentation provides you an easy way to show your slides in sync with your video. As you know, just making slides of your presentation available for someone who missed your talk is not ideal (in fact it's usually a bad idea). But if there was an easy way (without having to buy software) to show a video of your presentation and the slides in sync with your video then that would be pretty cool. Zentation does that. Zentation is not perfect, and for my kind of presentations it does not really work so well, but for people who have a relatively few number of slides in their talk, it seems to work pretty well.
Leave it to Guy
As always the presentation is only as good as the content and the presenter, regardless of how well the technology works (or doesn't), so I could not find too many great presentations on the site (but I didn't look too hard either, so let us know if there are some killer preso uploaded there). But leave it to our buddy Guy Kawasaki to put up a presentation that worked very well on Zentation. Even if you have seen Guy speak on the Art of the Start before, check this out. Again this is not ideal perhaps, but it's much better than just slides. Of course, if your slides and you are both clearly visible in the video, then Zentation would not be necessary. (I'm still looking for an easy way to pull off the effect of your local TV weather caster, where the presenter and large screen behind him are easily viewable).

Robin Good wrote an excellent, detailed review of Zentation back in April.
