I think style points would be an interesting addition to any game. If you can complete an in-game task in a unique way, you should get points (or maybe an award given to the team with the most in-competition points). Examples of such are special triple balancers such as Robonauts and Children of the Swamp. Or the teams that hung from the poles in 2010 (Cheesy Poofs, Simbotics, etc).

tl;dr: I think points should be awarded to a team that most uniquely and effectively pulls of a given task of the game.
