we usually put our logo on it. 2 years ago we cut the logo for our team into the frame (the logo is my avatar) and cut our team name into the frame as well (all of this done by oceaneering [our build site]). last year we cut our logo into the frame and spray painted all of our metal parts either green or left it silver (this was to distinguish one side of the robot from the other).
It was pretty cool.
