Internet videos to go with lessons?

I was wondering for those of you that write lessons for this site if you ever thought of adding a video link for the lesson? I know some people like myself are visual learners and it helps to see as well as hear what you are trying to learn. I know it's more work for you and might eat up bandwidth but I know there are others that are like me and need to see some of the lessons to fully understand them. (Not that I don't appreciate what you all do now!!)

Thanks
