Yesterday I wrote about my first screencasting test but I've now found something even cooler. It's called pyvnc2swf. It's a Python script that intercepts a VNC connection to record the screen. I haven't tried it yet but I will soon because as I mentioned in my previous post Camtasia Studio only works on Windows and I only use Linux.
If you want to see it used in action, check out Ian Bicking's screencast about ajaxy exception catching
