The art museum at Crystal Bridges in Bentonville is an amazing place with a huge amount of free art both inside and outside in their expansive gardens.  One of the larger rotating installations was called the listening forest.  The artist grew up above a night club and uses interactive lights and sounds to create art! (I can’t imagine how many computers are needed to control all of it!).  Jason and I went twice; once with my parents, and once with his.
