Not a direct copy of the KDE window decorations, but designed to look reasonable when used with the Breeze QT or GTK themes.
This is a fork. It includes minor changes to the original theme made by mostlyoxygen.
To install the theme, run:
git clone https://github.com/asdhio-github/breeze-openbox-theme/
mv breeze-openbox-theme ~/.themes/
