I immediately liked this video, shown at HP Connect London (link below). Thanks Adam for sending it in.
With the whiteboard "pen" drawing the activities, the reader follows along and in a sense is participating in the creative act. The reader is symbolically "going places" in the video with each new act of creation as well as literally. It gives a subtle experience of innovation and versatility.

I'd like to see a series of these videos.

I also hope this sense is carrying through to app creation itself.
