Hi, everyone! I created the following Linux/Unix-like desktop-environment theme entitled Computing Machine. It is for GTK+ 2/Gnome 2 applications; GTK+ 3/Gnome 3 applications; and Qt 5/KDE 5 applications via the Qt5 Configuration Tool ( https://sourceforge.net/projects/qt5ct/ ). The following is its OpenDesktop.org Pling page and its GitHub source-repository, respectively:
This desktop theme is intended to be visually reminiscent of classic desktop user-environments. See the included "Information.txt" file for instructions on how to configure this theme.
Already Computing Machine quite usable, at least with my desktop-environment setup. It was developed on the XFCE desktop-environment versions 4.12 and 4.14. I haven't tested it on other full desktop environments, just on window managers such as Claude's Tab Window Manager (CTWM), Feeble Virtual Window Manager (FVWM), Motif Window Manager (MWM), Tab Window Manager (TWM), and Virtual Tab Window Manager (VTWM), and it works quite well on them when the instructions in its included "Information.txt" file are followed. So on different full desktop environments, it may require some modifications to work well.
My intentions with this theme are to create a classic style of desktop theme while attempting to keep the code for it simple. As such, it doesn't attempt to make the GTK+ 2 and GTK+ 3 portions of the theme look exactly alike; but rather, to make them similar-looking in a retro style while keeping a consistent color scheme between them. Also to that end, this theme doesn't attempt to exactly mimic any actual historical user-environment theme, but instead is in the general pattern of them, e.g., sharp-cornered rectangle buttons and entry fields with solid-line pseudo-shadow edges; solid colors (e.g., no bubble-buttons with pseudo-shadow gradients); etc. This theme is intended to be practical in a form-follows-function manner.
For those who like classic-style desktop themes, I hope you enjoy!
