It's running on my [ctwm] desktop too.  It has two little arms (3,
actually, since I run it with second-level resolution), and little
tick marks around the outer edge.  I guess that's ancient, since
clocks looked like that well before my grandfather's grandfather was
born, but it seems to still work for telling me the time, so...
