"I also am overwhelmed by the wall hangings of the Ghanian
artist, El Anatsui. While I don't know which of these extraordinary,
enormous, vibrant, undulating works made with found liquor bottle caps is my
favorite, this is a prime example, "In
the World But Don't Know the World" from 2009. And you
need to see these pieces in person to fully experience them. For more on
El Anatsui and his work, see this NYT
article and the embedded slideshow
here." Jill Parker
