Chris Stones has an interesting collection of videos on his blog. Many of them are funny or experimental, some are about video editing techniques and I found one in which he shows how he uses Blender in his workflow as an illustrator.
In this video he demonstrates the process of creating a 2D logo with Blender. By using a curve, a Bevel Object (BevOb) and flat shading he can set up a shape that is easily modified during the remainder of the design process.
I have included this one not only because it showcases a different kind of use for Blender, but also because I think that this video is an example of a well planned and executed video tutorial. Chris obviously spends a lot of attention on all the elements: video, voice and editing, and his work is a joy to watch.
If you're interested, he has a number of (non-Blender related) videos on his blog, http://welcometochrisworld.blogspot.com/
