What are some basic/seminal artworks for either/or installation or netart?

I came back to Rhizome a few days ago. On the donation page, the Morphine Pill by Bunny Rogers and Filip Olszewski caught my attention, which then led to a study of Sister Unn's, their art installation for six months during 2011-2012. My grandparents owned a florist/wedding chapel and nursery when I was first born; my parents worked there for awhile - Dad in the nursery, and Mom doing deliveries and other things in the floral shop/wedding chapel. So Sister Unn's brought back some memories.

However, it took several links in a Google search before I found Bunny's explanation of what I was supposed to get out of the installation. I don't think I would have ever gotten that on my own. I find the same thing with netart, often I don't "get" what I "should." I realize reactions, thoughts, emotions, experiences and people are different, yet I'd like to sometimes at least feel that I'm on the same wavelength as the artist.

I have a dial up modem, an XP computer, and the wish to learn and understand. I would like beginning places or references or resources for installation art and/or net art, at least to begin with. I am going through Rhizome's archives with several searches.

If you would please point me in a right direction, I would appreciate it!

Thanks,
Theresa
