In September I did a LISterine workshop on Capture. That presentation was captured using various devices included an iPod with an iTalk Voice Recorder, an iPhone, SnapzPro, a Zoom H2 Handy Recorder, and an Accordant capture station
The screencast of the presentation included videos of iPhone apps (made up of iPhone screenshots). So I guess some versions of the presentation are captures of the computer projector which displayed captures of screencasts on a web site which in turn were captures of iPhone apps in action that consisted of iPhone screen image captures.
Included here is a screencast introduction on How to do it… (capture that is).
For an unedited version of this presentation that includes screen capture and video of me trying to figure out how to show this stuff, see: Digital Media Collections at Middlebury College
