I'm hoping to do some screecasts on various technical subjects. As I do them, they will appear here.
I generated a code swarm animation of commits to the d-i project with help from Frans Pop. I had planned to set it to music, but never got the chance. Instead, Christian Perrier used it during a lightning talk at DebConf9, and provided great commentary on the events shown in it.
I combined video of Christian's talk with higher-quality excerpts of my original code swarm video to produce this.

Not a screencast as such, this code swarm video depicts commits to ikiwiki.

This 15 minute screencast builds on the first, showing how to use a setup file to make ikiwiki support web edits via CGI, and how to use git with ikiwiki.
This is a bit out of date now; ikiwiki's tutorial explains a more automated way to set up a wiki or blog.

This 10 minute screencast demos how to set up a simple wiki and blog using ikiwiki.
This is a bit out of date now. The syntax for preprocessor directives has changed. Also, ikiwiki's tutorial explains a more automated way to set up a wiki or blog.
Apologies for the slow typing in places; I did this without a script! (I'm a two finger typist, if you must know. ;-)

So far, I'm using byzanz to record my screencasts as animated gifs (which are then converted to ogg theora).
Handy command reference:
byzanz-record --cursor -w 640 -h 480 screencast.gif --duration=3600
mkfifo stream.yuv
mplayer -vo yuv4mpeg -ao null -nosound screencast.gif &
