It's really really fun. I do it a lot, am not very popular doing it, but get good engagement. Especially when the topic is something visually interesting.

I'm now at a point where it feels weird coding without saying my thoughts out loud or writing them down on paper. Like I don't know how to think unless there's some output.

And when watchers highlight a bug or tell me techniques to try that I haven't thought of, amazing.

I need to make better use of scenes and staging screens like OP is doing. My streams are significantly under produced right now.
