The Creation of a Turret Clock

I see quatrefoils.  I see them all the time.

  My blacksmithing geekdom has reached a new high.  I am on a business trip this week and stuck in a hotel room.  ABC is showing Sixth Sense and I just have it on in the background.  Well, the scene happens when Cole gets locked into the attic by the two boys.  Cole is busy screaming, his mother pounding on the door and what do I see?  That's right, I'm looking at the iron door behind the mother.  Looking at the quatrefoils on the door thinking to myself that I could make those...  Not only that, I'm thinking that it may have come from the workshop of Samuel Yellin in Philadelphia, perhaps American's finest blacksmith who lived in the early 20th century.  Oh yeah, movie, plot, dialog...  stop looking at the iron work.
