The first piece is at the Cleveland Museum of Art.  I think this is a very fun and appealing way to teach people about other cultures.  In the picture, the girl is mimicking a statue that, most likely, played a major role in history.  I think that this art piece was a great way to attract people to the exhibit. It also made learning fun for the people involved.

The second image is not as meaningful as the first, but it is still very interesting.  This is more of a silly interaction.  Nothing is being learned; no information is being passed along.  This is why it is not as meaningful.  This exhibit is more for comedy and fun photo op appeal.

The third art pierce is the least thought provoking exhibit.  It is basicly just a playground that can comfortably fit adults.  The person experiencing the art is just supposed to have fun.  I do not think that there is any deeper meaning to this peace.
