Computers and robots are doing all kinds of nice, pleasant things these days, probably so that they can lull us into a false sense of security and jump us when we least expect it, from delivering Domino's pizza to, now, painting an original Rembrandt. The artistic computer in question is operated by humans from Microsoft and other organizations and it analyzed Rembrandt's works to determine that its subject should be—surprise—""a caucasian male with facial hair between 30 or 40 years old in dark clothing and a collar wearing a hat with his face pointing to the right," the used statistical analysis and algorithms to create one. While we're not sure if the master himself would sign off on the painting, the average museum goer would probably be fooled.
(Sidenote: Once, at a Rembrandt exhibit at the Cleveland Museum of Art, I overhead a woman say to her friend, "I just love all the colors!" which seems like one of the funniest things you can say about a series of Rembrandt paintings.)
