    This shot shows Sprog running under Debian GNU/Linux in the GNOME
    desktop environment.  In this example the gear palette is visible, two 
    gears have been dragged to the workbench and a third is being dragged
    across to complete a simple machine. |

    In this shot, the gear palette has been hidden, the assembled machine 
    is running and the results are appearing in the text window. |

    10.3 ("Panther") system. |
