Solar-driven golf cap
This is truly a gift for the man who has everything—and in this case, it was given to my friend and colleague, Bill—who gave it to me. The little fan starts to whirl when you’re out in the sun. It’s great when I’m out cutting the grass, although it has a tendency to fall off when I swing a golf club—which I don't do well at the very best of times!
