Ole Miss (or any school) Pocket Rosters.  Take a look.  I think they are pretty neat.

Basically is a Pocket Roster that will hold up all season.  Eliminates the need to carry a program - fits in back pocket, etc.  It's guaranteed to last the entire season.  Perfect for learning the freshmen and transfers without having to play the guessing game or ask the guy next to you.  iPhone's never work in the stands so you don't have to worry about that either. 

Simple, no doubt, but pretty cool.
