Here is a "video", or is it screencast, I made with byzanz desktop recorder and Ubuntu GNU/Linux. It's a short clip of me demoing some Open Office.org spreadsheet tips for a friend of mine.
Byzanz is so handy because it installs as a panel applet and records your desktop session to an animated GIF. You don't have to worry about video formats and browser add-ons/compatibility with GIF's. No sir, just add and image to your page and go on with living. :=)
Just when you think Free and Open Source Software can't be any more cool or useful, BAM!, you discover another nifty tool. What will apt-cache search turn up next?
It's hard to express how thrilled I am to have found byzanz. Now Free and Priceless can become a kind of show and tell for our FOSS exploration.
While I'm feverishly reworking potential blog post to include this wonderful technology, I'd love to get comments on your Linux/free software questions. Just post a comment on a screencast you'd like to see and I'll try to work it in.
