I've had to explain our architecture to new hires a while ago, and it was a real mess. I was screen sharing while talking and drwing an ugly graph in inkscape at the same time.
It gave me an idea though, I'm working on a project that'd turn a plain text document (dot language style) into an narrated video made up of graphs showing how things work, who does what when..
Idk if there's a market for that but it's really fun to program anyway :)
