Tab Window Manger a.k.a. Tom's Window Manager provided windows with title bars, something resembling icons (see the top left corner) and configurable key bindings. But no wallpapers or virtual desktops or other modern sugaring like widgets for closing an application.
Configurability and theming is kept to the minimum. One can change the fonts and colors but not much else. If you have a computer with Pentium processor I would suggest you to use any other window manager.
