My pasteable "scorecard" was fairly simplistic, just 8 solid green circles followed by an ellipsis. I think you could improve this by dividing the course into regions (either visibly or invisibly - same number of regions as the par) and considering each hit to be green if it makes forward progress, amber if it doesn't, or red if it goes backwards. And don't truncate it if it takes more than 8 shots!
