TempuraFlat GTK2, GTK3, Openbox and Tint2 Themes
This is based on a really old GTK2 theme, Tempura. I applied the colors and flat shapes to one of the excellent Bunsen themes. This was a manageable task for GTK2, but GTK3... that took me a while. The amount of config text must be about ten times of the GTK2 config text.
