Boy does that bring back memories of the 1990s!

Some of these are not obscure at all, but absolutely standard. Xterm was the shell, I’m not sure there were even alternatives in early X. Xbiff+Xload+Xclock used to be on everybody’s desktop. XV was the main image viewer on X for a long time.

Anybody remember xvacuum? I guess it’s truly obscure since it didn’t make the list. One of my favorite tricks to play on other people in the lab, before X security was a thing, was to run xvacuum on other people’s displays ... it slowly sucks everything on the screen into the mouse cursor.

If the page maintainer is reading, Xsnow has a calculator in the screenshot covering the snow. This one is a bit obscure, but I loved xsnow, so I think it deserves a calculator-less view! :)
