CamTwist - Multi-camera streaming for online lessons

In this video I will show you how to use CamTwist (for Apple/MacOS) to stream multiple cameras during an online lesson.
This works with Google Hangouts, Zoom, and Skype, and probably many other services.
This is a great solution if, for example, you are a music teacher and want to show your face, and the use of an instrument at the same time. Or maybe you are playing a board game and you want to show a close up of the dice roll.
Setup picture-in-picture streaming of two webcams hooked up to your computer.
Please share your tips for live online teaching in the comments.
