Since I last visited quite recently, there was only one new exhibit: Yinka Shonibare MBE. It was a retrospective of his work, and I found it very interesting, and fun too.
I like the connections Shonibare made to a triangle trade of sorts with the Dutch wax, which undercut African textile makers. A recent Economist article explained that imported Chinese textiles cost 1/3 the price of comparable domestically produced fabrics in Angola.

I also enjoyed Shonibare's view of the Enlightenment creating a justification for colonialism - bringing wisdom to ignorant peoples. So his conclusion was that the age of reason served as a rationale for subjugating others.

The exhibit was very accessible - good explanations, including some video of Shonibare describing his art and motivation. It's on until March 7, 2010, and I strongly recommend that you visit it if you happen to be in DC!
