"The Story" on APM had this piece:
Ken Perenyi paints like Rembrandt - and Modigliani and Picasso. He can forge a brush stroke better than most, and for a time he actually sold his works as originals in the big auction houses. He had a close call with the F.B.I., and now he makes pieces that are labeled as copies. He calls himself a "master forger," and he tells his story in his book Caveat Emptor: The Secret Life of an American Art Forger.
After the forgery piece there is a segment called Noun Project. Here is the description. If you get the MP3 this is part of it so you can decide if you also want to listen to this part.
Description of "Noun Project"
Edward Boatman started designing symbols to use in his presentations at work, and soon his library grew to hundreds of icons. Now, people around the world are sending him symbols – for the brain, a key or a prayer – to include in the library he has called the Noun Project.
