Enlightenment always had a pretty weird value proposition. In the very beginning, there was "fvwm-xpm" and early "E" prototypes. They were graphically crazy with a heavy focus on shaped Windows. There's still nothing quite like that weird steampunk/Brazil-ish theme they had. Probably for a reason.
Then they went both visually rather tame and scope-creepy (own graphical libraries etc.). At the beginning I was hoping that we'd get some kind of Amiga-influenced design sensibilities on X (basically a more "artsy" MUI), but that never manifested.
Yeah, I got introduced to it via some friends that were former Amiga users.
