A Happening Place!

You are probably bored with all my telescope photographs, so I am offering something different.  During my first day in Minnesota I went to the Minneapolis Institute of Arts.  I arrived late in the day, but was really lucky because that day the museum was open until 9 PM. There was so much going on in the museum.  I got to take a tour of a new photographic exhibit, by the curator of photography, there was another talk by an author, and at one point I looked down from the second floor balcony to see these people on their backs in a circle.  There was a woman leading the group, but I couldn't quite hear what this was all about.  They are looking up through the circular opening in the floor surrounded by a balcony at a painted dome ceiling.  They made an interesting design as seen from above, though.
