On the cover


 

The author of our optical-illusory evocation of Edna Skinner is a man we're proud to call alumnus-in-law: UMass Lowell and MIT grad Rob Silvers, founder of Runaway Technology in Cambridge, creator of covers for Life, Wired, and Geo magazines, and very nice guy. His first book, Photomosaics, is out this fall from Henry Holt.
