I wanted to try this screencasting thing out, so thought i'd go over a couple of techniques i like to use. I described this before in text, long time ago, but thought it might be easier to follow as a video...
Hope you find it useful, post any questions below.
please note: no masking was used in the creation of this video

--- edit:
my tutorial links are dead

I'll re-do them and upload to youtube sometime...
