Whew! This was the hardest video for me (by far) to make. I started this script on August 21, 2009 and I'm finally finishing this up almost a year later. I would encourage anyone who has any questions to make comments, I'll by happy to try to help because I think this is a very important, albeit very difficult concept to understand.
The format is a little different, I used a green screen for the first time, please let me know what you think.
After this, I think I need to start DeepLobotmy.com
Thanks for your patience!
