There is a game developer on twitch that uses his VODs (video replays) as a versioning system as he doesn't use anything. "Wait, what and why did I do this? Lemme look at yesterday's vod". It suprisingly works quite well and is more entertaining for the viewers to see what and how bugs get introduced.
And help it definitely can. For some people, pictures and motions are easier to remember and reason about, even in such a text-heavy area as writing code.
