After finishing the Boat performance I found myself surrounded with all of this pink insulation foam and began to wonder what is it about this material that is so evocative? So I turned to the OED to find out what it means, literally, and here is what it says:
1. The action of surrounding by water or making into an island; the fact of being made insular. Also, an island.
2. and fig. The action of placing apart or detaching from other things; the state or condition of standing alone or cut off; concr. an insulated object.
3. The action of insulating electrically or physically; the condition of being isolated by non-conductors so as to prevent the passage of electricity, heat, or sound. Also the degree in which a body is insulated, as partial, imperfect, total insulation.
It struck me after reading this that it actual embodied a great deal of some the political malaise that has gripped the U.S. Somehow we are insulated. The other images of the Pink City in various ways deal with this sentiment.
