One of the questions I had after my Adobe Acrobat presentation had nothing to do with Adobe Acrobat at all. Instead, an audience member wondered how I managed to include animated segments in my PowerPoint that made it look as though I was working live with the software.
The answer? Camtasia from TechSmith, the same people who brought you Snagit, a handy little utility that grabs screenshots. I've mentioned Camtasia before, as a good way to record training sessions. You can also create short animated gifs, which is the format I used to paste into PowerPoint.
There's another product out there for creating animated Flash tutorials called Wink. I've never used it, but it also records screen sessions, and it's free. It's a bit more complicated to integrate a Flash animation into a PowerPoint, but it's definitely do-able. If you've tried it, let us know how you like it!
Wink is a great product for creating tutorials or otherwise grabbing screenshots and then annotating / animating them. I've used it to create tutorials for using our e-learning system. The next version promises to include audio, which will enable voiceovers. Wink targets self-guided tutorials, but I suppose you could use it in a presentation as well, though I find nothing is better than walking through something live... until the server crashes.
