The second follow-up post to this (1960s era man in a easy chair pointing at a wall with the finger and the computer and projecting a dot of light onto the wall) video, is someone who has replaced the screen with the HTTP 404 error.
Please stop posting Twitter links here, as there are no login-wall workarounds anymore and therefore it appears to be against the site rules.
Works without being logged in just fine for me—what's the issue (aside from being completely devoid of content in this case)?
Many Twitter posts are threads, with multiple replies by the initial poster, and AFAIK you can't see any of the reply posts without being logged in. So without being logged in, 1) if the post is a thread, you can't see the full context, and 2) you can't tell if it's a single post or a thread at all.
