Jing (video capture software)

I read about Jing in Robert Hoekman's excellent book, Designing the Moment, and found it amazingly useful. Among other things, it lets you create a screen grab video. I used it to show a bug I was seeing to the tech folks on a project I'm part of. Picture's worth a thousand words, for sure....it would have been much more time-consuming (and less effective) to try and explain this in an email.
