Floating Head is an easy to use macOS app that will display the video feed of any internal or attached camera inside a round floating panel on top of everything else. And nothing else.
It allows you to add yourself to any, live or pre-recorded, screen recording without needing special editing software. All you need is FLoating Head and the built-in macOS screen recorder.
If you find a novel use case I would love to hear about it!
Then just start your screen recording, stream or live presentation!
