Nancy Holt's "Systems"

I just read "Systems" by Joan Marter.  In this article, Joan Marter has a conversation with Nancy Holt about her major "system" sculptures.  Nancy Holt explained that she was interested in the modern systems that we have all grown so accustomed to and in bringing awareness to the viewer through her sculptures.  Some of the larger systems she has tapped into in her work are electrical, water, solar, air, etc.  Of course, we're all familiar with her Sun Tunnels (1973-1976) in which she aligned her giant cement pipes with certain aspects of the solar system.  As viewers interact with this piece it is her hope that they become aware that they are connected to a larger system.

Here's a complete park that she designed which also references the solar system.  Dark Star Park (1979-1984):

People in this area tend to return every year on August 1st to see the shadows of the spheres and poles align.  It has sort of become a ritual for them.

Another sculpture talked about (that I wasn't as aware of) was Hot Water Heat (1984) in which she created an interesting (and playful) configuration of pipes in which hot water flowed in to actually heat the gallery.  I can't find a picture for this one, but if you go to the link below it will take you to the article that I read and there is a picture of it in there:

I also enjoyed reading about Water Work (1983-84) in which Nancy Holt tapped into the actual city water system and created an outdoor configuration of pipes that people could interact with.  It was her hope that, through this interaction, people would become more aware of where the water comes from and where it goes.  There is a picture of this piece the article as well.  I am surprised that there are no pictures of these sculptures on the internet.

Very cool!
