I got a message from richter of bryce5.com the other day.  He pointed out a render he'd done using Pro-Render; a cool concept tech-looking thing.  I don't think he posts here though so I'm including a link to the image.

I hope such renders will encourage more Brycers to learn the Pro-Render rules system.
