Flash is wonderful, Flash is good, not everyone uses it, but everyone should. And if you can't afford Flash I found a little app that lets you create presentations that turn into those nifty little SWF's. It's called Wink, by the good folks over at DebugMode. I've seen it used on several sites to demonstrate software. Not only does it grab screenshots (complete with cursor movement), you can also add simple buttons, textboxes, and titles. Just the thing for simple training videos. Did I mention it's Windows and Linux compatible?
