Charles Petzold has created a nice GradientPath-class that lets your gradient actually follow a path (say a curvy spline):






He also explains how he made this work. Frankly I'm always amazed at the creative thinking guys like Petzold manage to pull of. It also keeps me focussed on improving myself on a daily basis. Too bad there's so muc interesting stuff to choose from :(

Nevertheless, I think the GradientPath class is cool!
