This was a video I prepared, originally as part of the 2-Minute Tutorial series. But I never posted it, because:

1. it was not technically a tutorial,
2. it uses a lot of copyrighted source art I wasn't sure about publishing (even though this is almost certainly "fair use" as it's a critical discussion of art styles), and
3. I wasn't totally happy with the way I presented the information. However, I never got around to revising it to make it better.
