On occasion in the past, my group has voted on a Roleplayer of the Night award....each voting for the best roleplayer or coolest moment of the session by secret ballot. The reward was usually either a reroll or a small amount of xp.
Last Sunday, we wrapped up a two year run at Pathfinder's Curse of the Crimson Throne. One of my players created an awesome trophy to sit at the table in front of each week's winner! I thought it was cool enough to share...
