The featured article (article on Wikipedia's main page) for July 12, 2016 is the anime short film Katsudô shashin (1907?), a video of which is available in the article. I'd never heard about it before, but it's so remarkable to think of what a discovery it would be to come across the earliest known piece of anime in Kyoto in 2004. This is archaeoanime, a treasure find for film history.
Katsudô shashin runs at three seconds and features a boy in a sailor suit writing "moving picture" on a board in Japanese characters. It's extremely short by today's standards, but groundbreaking and, in its own right, is still adorable and good-natured.
A number of people here on IMDb have given Katsudô shashin low ratings, but I believe that's failing to take into account what the film is and what it's trying to do. As the late Roger Ebert said, "the star rating system is relative, not absolute. When you ask a friend if Hellboy is any good, you're not asking if it's any good compared to Mystic River, you're asking if it's any good compared to The Punisher." So, discover the joys in moving pictures.
