The most unique thing I've ever seen was done by 4451 in 2013 or 2014...I think.
They had a holographic HUD projected onto some plastic mounted perpendicular to the base control board. That way the drivers could watch the robot and see important information simultaneously. I'd like to see, or do that one myself someday.
Our driver-station this year featured a simple and yet very elegant control board. It had a custom arduino mega board that allowed us to not only send signals to the robot but also receive feedback to the control board through LEDs.
