Visually, NsCDE mimics CDE, the well known Common Desktop Environment of many commercial UNIX systems of the nineties. It supports CDE backdrops and palettes with FVWM colorsets and has a theme generator for Xt, Xaw, Motif, GTK2, GTK3, Qt4 and Qt5.
Integrating all these bits and pieces, the user gets a retro visual experience across almost all X11 applications. Enriched with a bunch of powerful FVWM concepts and functions, modern applications and font rendering, NsCDE acts as a link between classic CDE look and a fast and extensible environment, well suited for modern day computing.
