Ubuntu 101 for novices video or graphical tutorials?

[H.S.]

Hello,

As some of you might recall from my previous posts, I have introduced
some computer novices to Ubuntu. I handhold them now an then to show
them some mundane and basic tasks. I was wondering, as there any short
video or flash or graphical tutorials that describe the very basics of
Ubuntu desktop usage?

For example, how to move and copy files and folders, how to use the
mouse for copy, paste, editing, etc. Any pointers?

Thanks.
