Josh Lund (FITS) came across an interesting product at the NMC conference recently. The Swivl is an iPhone/iPad/camera base that sits on a table or mounts to a tripod, and then enables you to use your mobile device to record video. The recording can combine slides from your computer with the camera feed. The camera follows the remote control, so you can walk around the room doing a presentation and stay in frame.
The company offers a free 30-day demo, so this is something Josh and I will be taking a closer look at.
