An interesting interactive feature from a New York Times web page allows you to view and 'fold' Al Jaffee's Fold-Ins from Mad magazine. The Fold-Ins are located on the last interior page of the magazine (1960's to present). The reader folds the page as directed to reveal a second comical image in answer to a question. Instead of the significance of the viewer's position in actual space, it relies on the viewer to reconfigure the content of the two-dimensional image with a surprising new result.
