I keep thinking, also, about the art installation called Portrait of Ross in L.A by Félix González-Torres. It was at MoMA in San Francisco in 1998 and I’m pretty sure we saw it together. The installation is a recipe to be assembled again and again, across space and over time, as it appears in different museums: a mound of colorful wrapped hard candies, heaped against a wall, or in a corner, or gathered up in a pile in the middle of the room. Sometimes it is lit with a spotlight.
