>>17774729Windows 1 was flat. Kinda looks like TWM (by Tom LaStrange), an early X window manager. I kinda like it myself, and use twm when I have to "startx" for something that needs the bloated monstrosity.
Then there was MWM and Motif, which kinda look like Windows 3 (or is it vice-versa?) I guess it's okay, much better than the modern UIs made for phones and tablets.
