I heard two stories about this on NPR yesterday, and then there was a big spread in the Arts&Life section of today's paper.
Alan Bean: Painting Apollo, First Artist on Another World opens next week at the Smithsonian Air & Space Museum.
PRI's "The World" had a good interview with Bean.

After the end of Apollo, he eventually left NASA to pursue painting full time. He started painting scenes on the moon because he realized that was what he felt passionate about, and a friend pointed out that he's the only artist who's ever been off the planet. Eventually, he realized that his patches from his space suit were covered with moon dust and he started incorporating them into his paintings as well.
I would love to go to DC and see this exhibit. Unfortunately the Smithsonian website doesn't say how long the paintings will be on display.
