A picture is worth a thousand words, especially when you're teaching someone how to do something on a computer, and recordMyDesktop is a great little Linux application for creating screencasts. YouTube is full of recordMyDesktop screencasts showing all kinds of captures, including Beryl/Compiz in action. I lead a dull life; I'm not into ripping music videos or wobbly 3D bling, but I do like having a tool like this for good Linux show-and-tells. In this series we're going to learn how to create glorious Linux screencasts with sound and video.
