Athene is a desktop system for Linux that uses its own graphics drivers for high speed access to your graphics card. Because the Athene desktop and its applications have direct access to the graphics hardware, they have a significant speed advantage over conventional X applications. Athene is also backwards compatible with your existing X11 software. It features a highly responsive interface, scalable icons, translucency, alpha blending, Unicode support, and Windows compatibility.

You can also compile it yourself by downloading the source tarball (.tar.gz).
bbkeys is the keygrabber for the Blackbox window manager. bbkeys handles all keybindings and keyboard shortcuts for Blackbox.

It is highly configurable via the bbconf GUI utility, the included bbkeysconf.pl perl script, or via hand-editing bbkeys's config file.
