Just when you thought you've mastered Microsoft Excel--creating pivot tables, VLOOKUPs and the rest--you discover the feature you never knew was there. The one that lets you create Japanese landscape paintings. When Tatsuo Horiuchi retired, he found that feature and leaned on it, hard. Now 77 years old, he has enough landscape paintings to stage an exhibition--all made with the point and click of a mouse.
So what's the moral of this story? Maybe it's you're never too old to make art. Or maybe it's never too late to master those hidden features and push technology to the bleeding edge. In Tatsuo's case, he's doing both.
