We also visited Tacoma were we visited the glass museum.  Didn't know there was a museum dedicated to only glass art.

This is called the bridge of glass.  You can see the top of the museum on the right.  It is the cone shaped roof. 

As you walk across the glass bridge there are several ceilings with glass murals.  This is just one small square of a mural.
