Stairwell window

The following is in a stairwell.  The vertical lines are the railing on the other side of the stairs.

The hand rail is mounted into walls on either side of the glass and has a groove in it which rests on top of the stained glass.  Hand beveled glass and various textured glass.  I enjoy the flow of this design within the triangle. 
Laminated glass is on the stairwell side for safety reasons.
