Debugmode Wink is a freeware piece of software for both business as well as personal use for doing screencasts and incorporating sound into your screen captures. The main useful format it outputs to is macromedia flash though you can output to PDF for handouts and so forth. While its not a PostgreSQL related item per se,
it can be useful for making all sorts of tutorials including PostgreSQL tutorials that involve showing people how to do things on screen. We've started to experiment with tutorials of this
format and hope to get into doing
more hands on like tutorials. We'll probably be doing a using PostgreSQL in OpenOffice tutorial in this issue since it lends itself well to screen casting.
