> I imagine that there are a lot of people that would love to interactively share their knowledge/skills on youtube/twitch but avoid doing so because they're not conventionally attractive or just too shy.
Couldn't they just not show themselves on camera at all?
Project idea: Take something that looks like a mindflayer (d&d art with tentacles around it's mouth) and use it for live coding.
Instead of displaying a mouse and cursor have the tentacles reach out and manipulate the code from behind a semi-transparent pane of glass that the code is displayed on.
