NAME

       xdaliclock - melting digital clock

SYNOPSIS

       xdaliclock

DESCRIPTION

       The  xdaliclock  program displays a digital clock; when a digit changes, it melts into its
       new shape.

       This program was inspired by the Alto and Macintosh programs of the same name, written  by
       Steve Capps in 1983 or 1984.

       --root
           Render on the root window instead of opening an application window.
