Brian,
I agree students who wish to do additional work, on their own, beyond what is required should be recognized for their effort. I use a component point system which accounts for 100% of the points, so I can't give points to an unknown category. But I can call attention to the students work, give personal and public recognition, and perhaps let the student share their work with the class. It's interesting how satisfying a room of classmates' applause can be!
