How about this?
At some point I may design trophies for each category...and a second place trophy if there is a tie.
 I might use an image of the ship for the Episode Theme, image of the crew for TOS Theme and a off the wall image for the Random theme...I am going to use Kirk with Tribbles for a second place trophy. I might have these ready by the end of the next contest.
<< Like that with the winner's name of course...not mine.
[update] I will have the new trophies unveiled later today when I post the new entry thread.
