I am looking for a Linux desktop which look retro, but is still fully functional in the inside.
Ideally I'd like a desktop which uses (or simulate) the 16-colours mode of the old PCs. The applications themselves need not to be in 16-colours, just the window and the menus. I'd like something close to Windows 95, Windows 3.x or OS2/Warp in how it looks/feel and is used.
This has nothing to do about memory efficiency, I actually think that strong, vivid colours look much better than the gray/black fad we have currently.
(I am not interested in neither LXDE nor XFCE, while those are not retro enough, among other reasons)
